Rated 4 out of 5 stars

Hi. [O/S Ubuntu 22.04] Overall I have found TB Sync very satisfactory. However since the recent update of Thunderbird to v 115.7.0 (64 bit), I am repetedly seeing a screen asking for the password for my calendar. After I type in my password, the screen disappears for a few moments only to reappear once again. If I click on 'cancel' the screen also disappears but soon returns. After a while this becomes very irritating. I cannot tell if this is just a harmless glitch or if TB sync is not working properly. If this gets cured, I shall be happy to increase my rating to 5 stars.
