This is not a true bug but it does affect much the Android app usage.
The + button to create a new table is very easy to hit by mistake: when scrolling tables, when holding the phone on the right hand. Once I created like 10 new tables just by mistake.
I have these two options to suggest:
Undo could work for me. However I can’t completely agree with your comment as I have difficulty conceiving someone completely building a base and many tables using the app alone. Anyway, the only problem with Undo without further confirmation is that I have more than once created new tables and, not having noticed right away as I was working with the phone in portrait mode (not much room to see table names), I would have been too late for an Undo, I assume, especially if I took some valuable action right after.
