I have the Wikipedia mobile app installed on both my phone and my tablet (both Android devices), and I have seen a significant uptick in the last couple of months of notifications of a multitude of failed login attempts that seem to coincide with my having opened the app, perhaps with a less-than-reliable internet connection. Is this a known issue?

We haven't heard this before, thanks for your report. I created a bug ticket for it, if you want to follow it: phab:T179518
I have a question -- There's two types of notifications: are the ones you're getting about failed login attempts, or successful attempts from an unfamiliar device?
If the app is triggering them, I would think the "successful attempts from an unfamiliar device" notifications would make more sense than the failed attempts -- but if you're getting failed attempt notifications, then there really is something odd going on here. :)
