App issues and bogus security error- how do I get Actual help?

I showed up for my route this morning and after I clicked the arrived button and took my photo, a red error message saying "there's a security issue with your device" popped up preventing me from checking in/ scanning with the warehouse worker, and now continues to prevent me from accepting my incoming reserves.

The error message comes with a link to the Flex faq, which is completely unhelpful. I've been doing this almost full time for 2 years, nothing has changed with my account or device, I've never used bots or done anything outside the rules. I've done everything the help section suggests- closed the app, logged out, turned off my phone, deleted my app storage/cache. Calling support did nothing. I sent an embarrassingly unhinged email to the robots at flex support, too.

And yesterday my itinerary disappeared while I still had packages to deliver. Support just said they've been having lots of problems with the app...

Anyone know of a number to call where I could get actual help with this? Emailing has been 50/50 for me in the past. I'll often get some help but no actual answers. Would calling Last Mile do anything?

Has this happened to anyone else the last couple of days? The warehouse guy said it happened to another woman who tried to check in a couple cars ahead of me, so I'm guessing it's an issue system-wide.
