There was a problem with undo

Hi! I have been getting this undo error message over and over again for some time when i want to go back with cmd+Z. After that I cannot go back or forward in the glyph editing.
I’m using Glyphs version 2.6.5 (1342) under macOS Mojave 10.14
Is there a solution for this problem?
Many thanks in advance!

Try the latest beta please. Go to Glyphs > Preferences > Updates, activate both checkboxes and press the Update button.

Thanks for the tip. I’ll check if the error is gone now :+1:t2:
