I use a network calendar on my LAN that has the following URL:
TB portable cannot synchronize it because TB portable does not know how to open the URL: it briefly asks which app to use in a window ("How do you want to open this? Google Chrome, Internet Explorer, Microsoft Edge") that immediately disappears. The calendar is listed but remains empty.
I thought a ftp client was included in TB to handle FTP URLs.
The problem does not exist in portable TB 78.14.0 that is located on another PC with the same OS version and never updated. BTW my current workaround is to use TB 78.14.0.
Anyone with the same problem and (ideally with) a solution?
