Works principally fine but if I disable syncing of contact accounts it just reactivates syncing once I leave the app. But I want to have all contacts in one account and don't accidentally save them in one of the others, so I want to disable the synchronization of the other ones because my mail provider doesn't allow me to delete the other contact accounts unfortunately.

Almost good. Calendar sync works well, however, recurring tasks in the tasks app are lacking options. In the web interface I can select every 3 days, for example, but those tasks do not sync and the tasks app doesn't have same options. A bit disappointing.

The app was useful for syncing my calendars until it suddenly stopped syncing two weeks ago, with the error android.os.RemoteException: Unable to retrieve provider data for account

Paul Field

Four stars as calendars and contacts sync perfectly between my device and my provider. I can't comment on Tasks as no recurring tasks sync but Vivaldi on desktop behaves exactly the same so must be how my provider does CalDav

Very useful for syncing tasks and calenders including shared public calendars. Icon could be made more coherent with the files app. Needs read and write support for syncing contacts to work with full contact and contacts optimiser. The tasks app should be a sperate optional app and needs support for custom repeats such as every 3 months or such.

Phone widget for the Tasks stopped working about a month ago on Samsung s23. I tried reinstalling it but still nothing.... This used to be my favorite task app so I hope this issue will be fixed soon.

Calendar sync doesnt work and the terrible interface does not say why or give any information. Just a blank screen

please please please let ME decide if I want to use cellular networks for syncing. I'ts extremely annoying that the choice is offered, but the moment you close that tab, cellular networks are activated again
