Hello again.
Thanks for your update.
I appreciate the clarification regarding the use of the SharePoint Mobile App instead of the browser version, and the absence of Modern Lists and Libraries in your environment.
Regarding your question about the browser, the initial suggestion was based on a common scenario where Android tablets use the web browser to access SharePoint Online. Since you've confirmed that your team is using the SharePoint App, the issue may be related to how the app interacts with classic site elements, specifically, the "Hamburger" menu functionality in classic page layouts.
Unfortunately, the SharePoint App can inherit limitations from underlying classic experience, which may not always respond to touch as expected. At the moment, swiping remains the primary gesture to expose the menu when it's unresponsive to taps.
We've escalated similar cases and will keep monitoring for improvements to the SharePoint app's UI behavior on Android. In the meantime, you might consider guiding users on the swipe gesture as a temporary workaround.
Lastly, for further assistance, you can call our Support Team through the Customer service phone numbers - Microsoft Support.
Best Regards,
Daniel Coy
