Microsoft 365 IOS app issue with back button

There is a glitch with the Microsoft 365 app on iOS where the use of the back button is not functioning as expected.

For example, if there is a SharePoint site structured as follows:
SharePoint Site > Folder1 > Folder2 > Folder3 > Folder4 > Document.pdf

When a user opens 'Document.pdf' and presses the back button, they are redirected to the Main SharePoint Site instead of returning to 'Folder4.' This issue has only recently emerged and was not present in previous versions of the Microsoft 365 app on iOS."

Is this already reported as a bug?
