Sync problem: An error occurred while attempting to sign in
I have a problem with signing in to Opera in order to sync my data. I click "Sign in", fill in my email and password and press enter. First it seems to be fine, but then it says "You're currently signed in as: undefined" in the settings. Then it changes to "An error occurred while attempting to sign in". I don't know how to fix it, please help!
Same here. Works fine to sign in to Opera 45.0.2552.812.
Used to work in Opera Developer (until yesterday).
Same problem. Opera Developer (46.0.2590.0)
