Why is my Coinbase mobile app not working?

Hello, could you possibly assist me with an issue I'm encountering? I've been trying to use the Coinbase mobile app, but it seems to be malfunctioning. I'm not sure what the problem is, as I've tried restarting my phone and reinstalling the app, but neither seems to work. Is there a specific reason why the app might not be functioning properly? Could it be a server issue, or perhaps something with my account? I'd really appreciate any help you can provide, as I rely on Coinbase for my cryptocurrency transactions. Thank you in advance for your assistance.
