Bubble stops saving automatically if your internet connection is patchy and the connection timesout. There are only two signs of this - the message that appears initially, which could easily be missed, and the text that says ‘not saved’ or something like that in the top bar where it normally says ‘saved’. Don’t know what happened in your case, but if there’s nothing there you may have been working whilst data was not being saved to Bubble.
Same thing has happened to me in past so I make a habit to periodically check and refresh the page after long periods away from computer.
@yeong the timeout usually goes away after a few minutes though. If it was a long work session without you noticing that your internet connection was down, the odds of everything you worked on being lost are thin, imo.
Might be a long shot - are you sure you’re not looking at the live environment editor (where changes wouldn’t appear if you haven’t pushed to live)?
I’m actually realizing it’s likely due to me not having closed a separate open session on a different laptop. When I went back to my ‘work’ computer days later, the editor window was still open with an old ‘version’ of my app, and, I’m guessing, overwrote previous changes.
You’d think they’d have collision handled a bit better with delta and timestamp management but that’s my best theory so far
