ClickUp Problems & Issues

Users consistently report ClickUp being 'practically unusable — slow, extremely slow.' One user described it as 'the worst tool currently on the market' due to performance. On Safari it 'basically doesn't work at all.' Screen updates don't show for some users while others see them, causing sync issues.

Users report collecting '~50 ClickUp Bug IDs over a couple hundred emails with support' with 'an average turnaround time of ~8 months on bug fixes.' The platform has a public feature request titled 'Fix existing bugs rather than add new features' reflecting widespread frustration. Bugs range from minor loading issues to major data loss.

Users report missing assignment and comment notifications, desktop app notifications that never appear (ClickUp sometimes doesn't even show up in macOS/Windows notification settings), and browser-specific failures such as Brave. ClickUp has acknowledged a bug with non-@mention notifications on its feedback board. Missed alerts lead directly to missed work.

ClickUp tries to 'cram in so many features simultaneously that it feels like a cluttered mess.' New users find it 'overwhelming' with too many 'features, settings and customization options.' The same flexibility that makes it powerful also makes it 'confusing when first starting out.' Teams report spending significant time just learning the system.

Users report 'every sprint planning session is a pain' with issues across 'different browsers, OS, connection speed' where 'things load partially, they load and they are not updated.' Board constantly crashes or does not load. Sprint dates cannot be edited. This makes Agile workflows frustrating.

Users report 'the gantt chart bugs and dependency inconsistencies are costing us hours of time to manage.' Dependencies don't work reliably, making project scheduling unreliable. Teams needing proper project scheduling often find ClickUp inadequate.

The mobile version 'needs quite a bit of work - it's less intuitive and crashes often.' Users report the mobile app has 'terrible' support and doesn't match the desktop experience. For teams needing on-the-go project management, this is a significant limitation.

Users discovered that 'attachments, clips, and forms are all completely publicly accessible' because 'they have a link that anyone can access, even without a ClickUp account with no authentication required.' This is a serious security concern for teams handling sensitive data.

ClickUp reclassified guests from inside your company as limited members billed as paid users (only external guests stay free). Reddit users report bills doubling, e.g. $400 to $800, and one found an annual bill jumping from $144 to $1,250, prompting several teams to look for alternatives.

Guest seats are a commonly overlooked cost driver. Unlimited includes 5 guest seats for the first paid user plus 2 per additional user; Business includes 10 plus 5 per additional user. Beyond that allocation guests cost extra, which enterprise buyers report can add 15-30% to total contract value.

One user was 'locked out of the Notes feature without warning, requiring an upgrade from $10 to $19 per license.' Recent billing changes have left teams 'staring at bills that have jumped tenfold.' The Unlimited plan price increased from $5 to $7 per user.

ClickUp Brain AI is sold as an add-on: about $9/user/month billed yearly (around $14 monthly) for Brain AI and $28/user/month yearly for Everything AI, stacked on top of the base plan. Heavier use also burns AI credits, with extra credits sold at $10 per 10,000. A Business seat at $12 can end up at $21-40 per user once AI is added.

In October 2026 ClickUp's pricing page shows some visitors a new lineup: Core at $9/user/month yearly ($12 regular), Business at $17 ($25 regular) and Max at $100 ($120 regular), with pooled AI credits included. The tested Core price itself rose from $8 to $9 in mid-October. Prices you see may depend on your test group, which makes budgeting harder.

Users report 'it takes time for them to reply, or users are unable to speak to a real person.' When reporting bugs, ClickUp often says 'they cannot reproduce the issue' even when users have video evidence. Support described as having 'confusing policies, no communication, and a total lack of accountability.'

Users on ClickUp's feedback board report tasks that never appear in Google Calendar, dates shifted by one day, edits made in Google reverting to ClickUp times after ~10 minutes, and changes taking over 24 hours to sync. ClickUp's calendar team acknowledged overdue bug fixes for Google and iCal sync.
