OK, linking to calendar in web version now worked. But still I don't why the connection between doit and google was interrupted.

@grabarz
Thank you very much for your feedback!

What is the situation now? The connection between Doit.im and Google works in web version, but does it work on iPhone?
You mentioned interruption, but just after 2 minutes the connection came back, right?

Look forward to your reply so that we may ask our engineers for detailed analysis.

Now I have message saying there is no linked calendars in desktop version (Mac). In web version and iPhone version I can sync calendars without problems. Could you please check it up?

@grabarz You mean you see no tasks synced from Google Calendar in Doit.im for Mac but the tasks can be seen on iPhone version and Web version?

I have such a warning in Mac version (attachment). The sync in web version and mobile version works well and there is no message like in desktop version.
