I was adding multiple email addresses to Firefox Monitor on my PC in Chrome. I was signed into my Firefox account. I was able to validate most of them through the initial email that is sent by Monitor. However, after I just tried to validate one of my email addresses, I am given the error message: Error must-be-signed-in I then tried to sign in, but it spit out the same error. I tried clearing cookies & cache, used incognito mode, tried Edge & Firefox on my PC, & then tried Firefox on my phone, & I am still given the same error. I even tried using my LTE instead of Wi-Fi to see if it was a network issue. None of this worked, so I am left assuming it's either an issue with my own account or with Firefox Monitor itself. I tend to use unique email addresses for most of my online accounts using one of my own personal domains, so I ended up loading quite a lot of addresses into Monitor. Is there a limit to the number of addresses that I can add? Or is the problem something else? Thanks!
