Problem: The change-highlighting feature is available but only partially.

First of all, to activate the feature, I need to take the following steps on Windows.

1. Open the OnlyOffice DocSpace on the browser
2. Open a document
3. Go to "Collaboration" tab
4. Click on "Version History"

When I view "Version History" on the Android app, the feature does not work.
When I click on the three-dot menu next to each document, click on Properties, and click on "Show version history", the feature does not work either.

Besides, even when the feature is active, it highlights only ONE author's text.
When there are five authors including me, only user C's text is highlighted.

Why do I need it?:

I am writing three documents with 20 users. They read and edit them without informing me. To catch up with their changes, I would like to review who added which text.

I find it ineffective to activate Track Changes mode. It would require me to approve each new text and format change, which is complicated and unnecessary.
