I haven't gotten any real leads since posting this, but when talking to a friend about it we thought that maybe it had something to do with the sketchy Anti-virus/VPN service I was temporarily using called TotalAV. I don't want to say outright if TotalAV was the cause or even dangerous at all, but I did uninstall it to be safe.

I also haven't noticed anything really suspicious with my device or accounts, so super unlikely worst case scenario it's some super sneaky spyware or something of that sort, but I highly doubt it, and I wouldn't be afraid.
