Participant annotations appearing in wrong place

Hi all. I am a tutor, and I have been using Zoom on my ipad for years. Recently, when sharing a worksheet from my files, the annotations from my students appear in the wrong spot on both screens. This is so frustrating. I have tried all the bot solutions, and I even purchased a new ipad, thinking my device was the problem. I never had a problem before the new year. Any help would be appreciated.
