u/Equivalent-Speed-130

I've tried twice to get on with Prolific. Both times I passed the initial screening and I accepted the invitation. And both times I couldn't get through the registration. Last time they told me I wasn't on a trusted network, whatever the hell that means. And today I couldn't get past the phone number verification.

I'm in the US. I have Verizon Fios for Internet. No VPN

And I have had the same mobile number for 20 years.

Can't figure out my problem.
