Hi folks!

Here are the steps to reproduce this issue:

1) open MobileSheets for iPad on an Apple Silicon Mac
2) ... > Settings > Backup and Restore > Backup Library
3) Select a Backup Destination > Local File
4) Accept default name > OK > OK
5) Let it build the backup and then prompt for where to store it
6) MS opens up the backup directory that I have used previously. Don't change anything.
7) Click Save
8) The below error message about "not a directory" is presented. Click OK
9) Repeat (7) or any of the above, and (8) will continue to happen
10) Back at step (6), CHANGE THE DIRECTORY to something else, and then change it back to the original, desired value
11) Click Save
12) Now it works

Maybe something's not getting properly initialized until you change and then change back?

Thanks!!
