PHONE APP wont work

Hamalert app used to work on my phone, and now won’t let me log in. I can log in on the web just fine.

I have deleted the app and reinstalled it, but no luck.

Could you post some more details please, i.e. do you get an error message when you try to log in through the app, and if so, what does it say? Perhaps a screenshot would also clarify the issue.
