Are you saying that you can't create Proton email account or just Proton crypto wallet?
I can't create a Proton account to get to their wallet
[unfortunately].
The last time I used their service there was a link for the wallet without me having to do anything. Is the problem affecting new or existing accounts?
You probably had an account with them before clicking the link in question. I'm still unsure if it's limited to new users or just happening to me.
This looks like your IP was blacklisted. Try a VPN or appeal as instructed on the screenshots
I already tried with a VPN and different browsers and @icopress was kind enough to send me an invitation... I was able to go a step further by receiving the codes, but another error popped up:
Unsupported region [I'm getting this error while using a VPN connection from a supported region, so Looks like I have to make an appeal and see how it goes].
