I'm guessing you may have the option to force the single page display enabled in the annotation editor. Open the annotation editor, tap the three dots at the top right and then Settings, and see if you have the "Use single page display mode" option checked. If so, uncheck that and you shouldn't see the issue. MobileSheets is reloading the page, so there are only two things that would cause that - the switch to the single page display mode, or if you have "Allow editing of embedded PDF annotations" checked. If the second option was enabled, you'd see the same issue with the single page display mode, so that's why I don't believe that is the case.
