When trying to login to addons.mozilla.org to add add-ons to my collection, for Firefox Nightly - it prompts me with an e-mail verification. This mail is never sent to the specified address, no matter how often I retry. I just can't seem to enter accounts.firefox.com on Firefox, on my Android device. Ironically, there are no issues logging in using Chrome, on the same Android device, nor on other (desktop) devices. They just ask me for my 2FA code and then I'm logged in. - I did not forget my password - I have two-factor authentication using an authentication app (Google Authenticator) - I did previously manage to log in to accounts.firefox.com (months ago) - I'm running Firefox Nightly - the latest available version from the Google Play Store - I'm signed into Firefox Sync in Firefox, with the same account - I'm also using Lockwise, with the same account I don't know when this started, as my last login was months ago, before my botched attempts yesterday.
