It seems that changing internet connection doesn't affect and since the issue related with all android device and I suspect there is compatibility issue between android device and Office 365 app version. And I'm afraid to find out the root cause of this issue need to collect the log report your user end and help you further remotely.
As this Forum community has limited resources, the backend support team there has more permission than us, they have more resources to investigate the issue from the backend, they have Escalate channel to escalate your issue to check more and collect log reports for the root cause.
I understand how important it is to get this issue resolved. In this situation, we sincerely recommend that you Microsoft 365 admin, can follow the steps in this article and open/create a support ticket with a Microsoft support engineer, who will work with you and if required they can escalate the issue to the appropriate team by gathering log information. This is the standard procedure for addressing your issues.
Note: To create a support ticket, you need to have Microsoft 365 admin privileges and if you aren’t admin of your Office 365 organization, please contact the admin of creating a new ticket.
