## Updates from Amplitude
### 2026-03-27 15:52 UTC: investigating
For some flags, the exposures chart is not loading properly. For some experiments, the analysis page is not loading properly saying "This experiment's user property is not available yet. It will appear after users are assigned." and "Invalid user property gp:". We are working on a fix.

### 2026-03-27 16:42 UTC: identified
We have identified a fix. We are rolling the fix out.
