Hey Rumz, Ive been having the same issue for the last few days now and had the same troubling experience with support as well as the subreddit. Heres what I ultimately did to fix the issue:
I determined from some other comments on here as well as my own testing that it seemed to be network related. I (and many others apparently) were having the same issues, but they were fixed when I was using the mobile app on my data, but it stopped again when connecting to my home internet. After some troubleshooting, I figured out that by giving my network a new public IP that I was then able to fix the issue. I essentially had to reassign my router to a new MAC address, so I just told it to use my computers, then rebooted the router, and after that was done, unplugged and re-plugged in the modem, which fixed the issue as I now had a different public IP. There may be other ways to do this, but this was the most straightforward solution I could find. Hope this helps
