I got it to work by restarting my phone. In the end, although I had the latest version of your app (or so it said), it did not work until a phone restart. It had nothing to do with any other setting, be it network, router, wifi, you name it. That was irrelevant. The update you performed today, May 14, to the Android app + a phone reset is what fixed the issue. For anyone else with these issues take note: do not go about resetting everything on your home wifi setup to oblige this problem. It is most likely your phone app + needing a restart.
There are several hours of my life I’d like back 
I hope this helps somebody else. Too bad you’re not like Xfinity or I’d feel entitled to ask for at least a statement credit
