I can sign into firefox sync on android but firefox on windows fails to sign in, it says unknown account.

I am using the sign in to sync button in firefox itself..

I didn't had this issue before..so this is something new to me...

Hey it's fixed! I reinstalled firefox and then refresh it

Reinstall alone didn't work, but refreshed after that and now sync is working again..
