AppSheet Performance Issue – Slow Synchronization Recently

[hien_nguyen]

Dear Google AppSheet Team,

Over the past two weeks, we – the AppSheet user community in Vietnam – have noticed a significant slowdown in synchronization performance. Previously, my apps typically completed syncing in just 2–3 seconds, but now it often takes 10–12 seconds or more.

I have tested this across multiple apps and accounts, and many members of our community are experiencing the same issue, whether their apps use Google Sheets or Google Cloud as the database.

We are unsure if any recent changes to the AppSheet platform may have affected its stability, but we kindly ask that you investigate and address this issue to restore stable performance.

Thank you for your support and attention.

Best regards,

So far, no response back from Google team since yesterday. (x.x) 

Slowness of our apps still continues. To make things worse, there are bunch of errors are happening to some apps which are using MySQL as data source. Definitely there is a glitch in AppSheet server, but unfortunately this error is not seemingly attended by anyone in Google.

I just started having a lot of trouble simply saving an edit.  The editor is returning a vague message that it could not save the file, when in fact it did.  If I try to continue editing I will start getting version issues.  So I have to close the editor and open the app again to load the new version.  Sometimes it won't save at all.  Rarely it will actually just save.  Started about 2 pm EST on 6/12/2025.  I'm out of NYC.  My workflow is significantly affected.
