What kind of changes are you making? Also, I am very surprised to hear that about the history! If you have an example of this issue that’s captured in the version history, can you send an email to support@anvil.works with:
- The ID of the app (you’ll see it in the title bar)
- A description of which form has disappeared, and the corresponding entry in the version history (eg "it’s there in the history entry at 13:19 US Eastern time, but gone in the one I saved at 13:21), so we can extract it from the logs
I’m tentatively moving this thread to Bug Reports, pending further investigation
