Handwriting location error during zoom class

[꼬꼬꼬]

I use Zoom to do math classes.
It is a method of solving problems with each other on the file after sharing math books with students.

Since last week, the handwriting I've been writing is fine, but there is an error in the handwriting written by the student, not in a place where the handwriting was taken, but in a different location.

Error letters are usually moved up to the left in a smaller size.
Both teachers and students tried it on iPad, and it's the latest version of Zoom.

I took pictures and videos, but I'm sad that they weren't attached.

Anyone know a solution?

And I want to complain about not being able to take classes for two weeks due to an error at ZOOM  headquarters, where should I contact them?

Hi @꼬꼬꼬 may I ask if you encountered this issue within Zoom Docs or Zoom Whiteboard shared during a meeting? Zoom Docs has not supported hand-writing as of now. Therefore, I’m double-checking with you.

If it's an issue with Whiteboard, you are super welcome to drop a note here at Whiteboard's dedicated forum!  https://community.zoom.com/t5/Zoom-Whiteboard/bd-p/Whiteboard

Thank you for your feedback!
