Unable to connect to server?

On Android.

Anyone else getting this message when trying to open the game? I tried a few hours ago and the message popped up. Thought there might be some maintenance and decided to try again a few hours later but still getting that message. I Didn't see any notices on the website about maintenance either.

I've got an internet connection.

Tried verifying tile integrity. Nada.

Do I just have to uninstall/reinstall? Had a similar issue a couple weeks ago and doing that helped. Really frustrating, though, as it resets all settings, filters, red dots, etc. And my internet is slow as molasses.

Thanks!
