Mixpanel Session Replay Not Working

How to fix it

Try these in order — the most common fix is first.

1. 1. Check plan and allowance

   Copy steps
   1. Open the pricing page; Make the Switch means an older plan
   2. Free has 10K replays/month, Growth 20K; extras need an add-on
   Did this fix it? Yes No

2. 2. Check sampling and SDK

   Copy steps
   1. Raise the baseline sampling rate or add conditional rules
   2. Use JS SDK v2.61.0+ to record across page loads, v2.77.0+ for cross-origin iframes with record_allowed_iframe_origins
   3. iOS and Android need the Session Replay SDK
   Did this fix it? Yes No

3. 3. Fix blockers and proxy

   Copy steps
   1. Allowlist mxpnl.com
   2. Set lib_base_path along with api_host
   3. Forward Authorization and Content-Encoding headers
   4. Wait about a minute for new replays
   Did this fix it? Yes No

Symptoms
