When using the program normally, indesign will periodically delete ALL history between the current action and "Open" and erase it. Often within seconds of performing said actions. This has hamstrung all functionality of indesign in the context we use it for.

Reproduction: Normal Use

Version: Indesign 20.5.1

Expected result: History stretching back to document open, related undo/redo functionality

Actual result: Not that. No document history besides open, no related functionality.

Attached file shows a document that had been open and actively worked on for 3 hours prior to viewing the history panel, as well as the history actions being removed in-use.
