SharePoint/Word: Change in permissions turns off autosave.

Hi,

We have the following issue:

• In a SharePoint, to which users get access based on access groups, users have Edit access to Word docs by default.
• When the user opens the Word file in Word desktop the AutoSave is turned on. When you change to review yourself, AutoSave is also turned on. This works correctly.
• However, when the permission to the document is changed to Review before sharing and the user the doc is shared with opens it, the AutoSave is turned off when opened in Word desktop. Users are able to choose Edit anyway to continue editing and then the AutoSave turns back on.

My question is: is the AutoSave turned off by switching the permission to Review? If so, how can we change that this does not happen. Or is it supposed to work like that?

When searching online and in the MS community I cannot find a clear answer on if it supposed to work like this. Some say Review turns the AutoSave off, others say it should not.
