I just switched primary email addresses and am updating all my vendors. Im using Protonmail and Im on the latest version of Firefox on windows10. Im able to log out/in NI account pages on Ffox without any trouble. But when I try to validate the new Protonmail address, I get "address could not be validated". NA is now refusing to run or let me log out/back in because it picked up the new Protonmail address.... but it isnt validated.
Anyone have any experience registering on protonmail, or with any website issues on Ffox? Thanks
Edit: Ive tried multiple browsers and also a mobile device. I get the same error on edge, ffox, chrome.
