Steps to reproduce:Set up a Caldav calendar (mailbox.org here). With DAVx5 connect to this calendar. Cause an sync error. In this case deleting a recurrent birthday reminder caused an error 403 (Forbidden) from the server.
Current behaviour:DAVx5 writes a log file with technical error information (e. g. HTTP request and response, technical device information, Java stacktrace). The information might help the developer, but it doesn’t help a non-tech user at all. The information about the failure appears as a tiny icon in the status bar only, where it can easily be overlooked.
Expected behaviour:DAVx5 informs the user in a visible message, in understandable, non-tech words that it could not synchronize, which item is affected (the displayed name of the contact, date or task), what caused the error, how he/she can solve the problem and go on. For instance see https://www.nngroup.com/articles/top-10-application-design-mistakes/, chapter 3. If the log file is needed for the developer, DAVx5 helps the end-user with easy-to-follow steps to send it to the developer.
