Hm. You may have sorted this by now, but it sounds like you've got an old version of that workflow? I just ran my regular back up with this one: and all seems well...

@technoway Python actually has a built-in limit on how deep the Python call stack can go. You can get the current limit with sys.getrecursionlimit() and change it with sys.setrecursionlimit(limit). The default limit is 1000, which is normally enough that you don't overflow the native stack even if you hit the Python recursion limit. In Pythonista that seems to be too much though, if I run an infinitely recursing function with the default limit, Pythonista crashes. With a lower limit (such as 500) I get a Python RecursionError as expected. I have no idea what the size of the native stack is on iOS, but it's probably lower than on Mac.

Hello.. i also faced same as above.. n just solved.. thnx buddy

It seems that the undo button is back on the iPad, and the "pressing enter after an empty space" issue is gone on both the iPad and the iPhone. A couple issues still remain, but this is great. Thanks.

I renamed that file and now everything is working fine. Thank you very much for your help.
