Text deletes itself on Pages

I’m writing in Pages on IOS and stop for a moment. My fingers are only on the back of the phone and suddenly a bunch of text starts to delete itself very fast one letter at a time (as if I were holding down the delete key on the keyboard). This has happened a few times over several days. The only thing that stops the deletion is to press the Done button, or it deletes the entire document. The deleted text appears to be gone forever because you can’t Undo after pressing Done.

I’ve opened the documents in both iOS and MacOS. I’m not sure if I experienced this on the Mac too, but it definitely happens on iOS. I haven’t experienced this bug in other apps only on Pages.
