I am running Thunderbird 102 on Linux Mint Cinnamon 21.2. I have 16GB RAM, 500GB SSD, Intel Core i5-7200U CPU the problem is everytime I start Thunderbird the calendar asks me to provide my google account logon details. It used to remember this information. I can download and view new emails without having to provide logon credentials. I have tried: Logging into the calendar with different Google Account details (I have 3 email addresses) Restarting my computer Updating computer Updating Thunderbird (there are no newer updates available) Looking for an option in the calendar to remember my login but there doesnt appear to be a setting for it Removing Thunderbird and related profiles Changing to a different calendar (Open Google Calendar / Google Calendar Plugin). All to no avail. Any ideas anyone?
