Quick question - I watched your video, and I see what you are describing, but if you try to tap the undo button while it appears disabled, does it not work? I just want to verify whether or not it's a visual bug (i.e. the undo still works even if it appears disabled). 

You may have seen the annotations redesign that is being beta tested (https://www.zubersoft.com/mobilesheets/f...1#pid30271). I am about to start porting over the changes for the e-ink version, but once that is complete, I will verify that this undo issue is not a problem with that version.

No, it's not just visual, it definitely doesn't work ...
BUT I also have color Samsung tablet with the regular MSP version and the undo works properly.  Is that an e-ink problem then? Is that what you meant about the refresh thing on e-ink devices?
If that's case, how come this is not a problem with say, the default 'Notes' or the 'Reader' apps that come with the device?
Anyways, I'll take a look at the beta new version.
