Thank you very much for your feedback!
We've checked to find it work well now, please check again.
If any further questions, please feel free to contact us.

@_nonno Thank you for your screenshot. We're sorry but we've checked again and not found the problem. Could you please unlink Google Cal and relink to check if it works?
Have a good day!

@_nonno If you deleted it, you may relink it. Could you please check with the following steps to see if it's the same with your operation:

Please go to the Settings page on web version: https://i.doit.im/home/#/settings/account , click two buttons:
1. Click “Link to Google Cal, which is used to sync tasks in Doit.im to Google Cal;
2. Click “Modify the reverse-synced calendar lists”, and choose a calendar of Google Cal, which you may use to sync tasks from Google Cal to Doit.im.

Having finished the above settings, you may see the two sides can sync each other’s tasks. If you want to see the latest data of Google Cal in Doit.im, just click “Sync GCal”. It’s because there are quotas for Google’s sync, that is, it is unable to transmit data automatically to other apps from time to time.

Any problem, please let us know.

@_nonno Sorry for the problem!
Could you please provide us the screenshot of your Google cal so that we may check if "Doit.im" appears in Google Cal list?
Nice day!

@_nonno Thank you for your reply!

But from the screenshot, we can't see the Doit.im list in your Google Cal. There should be such a list shown in the column of Google Cal if the bi-direction sync is set correctly in Doit.im Settings. Maybe you have deleted the list from Google Cal by mistake, or there is something wrong. Could you please unlink Google Cal from Doit.im, and relink it again? -- as follow:

Please go to the Settings page on web version: https://i.doit.im/home/#/settings/account , click two buttons:

1. Click “Link to Google Cal, which is used to sync tasks in Doit.im to Google Cal;
2. Click “Modify the reverse-synced calendar lists”, and choose a calendar of Google Cal, which you may use to sync tasks from Google Cal to Doit.im, and click 'Save'.

Having finished the above settings, you may see the two sides can sync each other’s tasks. If you want to see the latest data of Google Cal in Doit.im, just click “Sync GCal”. It’s because there are quotas for Google’s sync, that is, it is unable to transmit data automatically to other apps from time to time.

If any further questions, please feel free to contact us.
Nice day!

I accidentally deleted the list from "Google Cal"
I decided to unlink "Google Cal" from "Doit.im" and link it again, but it was useless.
I am synchronizing to a sub account now. It is linked with no problem.
It is troublesome, but I will work with multiple accounts.

Another problem is that task addition via email is not working.

We have not yet resolved the issue of adding tasks by e-mail, and GoogleCal sync bugs.

The trouble of the mail is temporary and it is resolved now, but "Google Cal" has been out of sync for two months already...

@_nonno Thank you!
The problem related to Google Cal has been tested for several times, we can make it reappear sometimes but not every time. We've been trying to find out the cause.
Really sorry about the problem.
