There is a little bit of delay with scrolling because I had to disable A2 processing. The reason is that, if A2 is enabled, which allows for smooth scrolling, 2 seconds after you stop interacting with the screen the tablet will do a complete screen refresh, which flashes black and then white. This is extremely annoying, because it occurs if you scroll any of the lists even the smallest amount. So I opted to turn off A2 processing for the lists, which means the scrolling stutters much more (typical performance for an e-ink device), but it doesn't flash in your face when you release.
I don't think there would be a significant difference in performance between the Boox Max 2 and Boox Max 2 Pro as far as MobileSheetsPro is concerned. I can ask my contact at the e-reader store (https://ereader.store/en/) about this, as he has tested many different e-ink devices.

Update: My contact said he has been testing only on the Boox Max 2, and it works great.
