Im using Opera and Firefox (2019) and have detected issues with Speed dials

Im using the same email account and I see they dissapear a lot of dials and they dont ask anything, by the way Im still stay in the free account (not paid one) and I already manually added dials in both browsers, and I was planning to buy the membership (paid option) but this really sucks and Im writting this to the other users that be aware of this because this app do what they want without asking the user, my recommendation is If you use 2 browsers or more put different email accounts in them to stop the massive deletion of dials without asking
