Same here, I thought I was being hacked or something. I tried restarting my phone and everything then I was like it must be a virus. Then I read the whole certificate third party thing and was trying to figure out if a hacker made another rpn but it was working fine on my laptop so I couldn't...
The exact same thing is happening to me on mobile but on my laptop it's just fine. It says that my connection is not private and something about a certificate being verified by a third party.
