Merry Christmas. Leo Akari
Thanks for using Microsoft products and posting in the community.
I would be honored to help you with your problem.
I realize that you've encountered a problem of Microsoft 365.
Based on the information you have provided.
Your issue is not caused by Microsoft 365, but by the fact that you have not set a default browser on your phone, or you do not have a browser on your phone.
As Microsoft community mainly provides technology and support for office, it is difficult to provide you with technology and support for Android phones as Android and Android phones are not Microsoft products.
Here are some alternatives you can try:
Copy the link on the file, open the browser of your phone and paste the path on the browser to access it.
Or you can download a chrome browser on Google play and see if your problem is solved.
You can also reinstall Microsoft 365 in Google play to see if there is an issue
Best regards.
