Hi, thanks for reporting this issue. I think this is already fixed in our development version and, if this is the case, we’ll surely ship the fix with the next update.
I’ve been having the exact same problem on iOS version 2.0 (11093). I’ve tried restarting both the app and my phone but the app still crashes every time. This is only true for when I’m using the format keyboard though, using the three dots to delete the last row works just fine.
Edit: I think I might have slightly misunderstood the reported problem. But my problem is anyway deleting the lowest (not necessarily the last remaining) row in a table with the format keyboard, causing the app to crash
