Just missed a meeting today because I accepted an event on Thunderbird this morning, that should have synced to Nextcloud, and then to my phone running a calendar app from 'simplemobiletools'. Never made it. After I missed the meeting I didn't see the event on nextcloud, then went to look at the event on thunderbird, and now lo and behold its on nextcloud, two hours after it was over. Cool. Still not on the phone.
Anyone have a solid calendar stack they like? I'd like to reliably get from emailed invite to alert on my phone.
Heads up about SimpleMobileTools - the project sold out and some of those apps are no longer being updated, I'd suggest migrating your data over to the forked apps now maintained by the Fossify organization
Thank you for pointing out Davx blindly follows NET_CAPABILITY... which calls home. I avoid data mining apps but don't have a firewall to protect from these cases, may I ask what you recommend?
The problem isn't with Nextcloud (I had the same issue happen with me). The problem is with the default sync settings on Thunderbird and DAVx5 (at least for me). Thunderbird defaulted to a longer than I wanted synch schedule, so I dropped it down to syncing every 15 minutes. DAVx5 was set to 240 minutes unless the event was created on my phone. Once I updated both schedules to every 15 minutes, I haven't noticed an issue.
The problem is not that the clients suck, the problem is that you're using Nextcloud. Switch to something like Radicale or Baikal and it will all work fine.
