Eraser & Textbook suddenly popped up when share screen

[PN99]

Hello,

I am using the latest version of Zoom Workplace (annual subscription). When my client shares their screen and I write on it using an iPad, they often encounter a textbox or eraser tool popping up unexpectedly. When that happens, they can't type or write anything. This issue persists until the client stops and reshares the screen. Could this be a glitch?

Hope to hear from you soon.
