🧩 What happened?
I've got at first Sync failures for the automatic sync (Won't report for now, as there was the update Today). But the Failures won't occur when I Trigger the Sync manually.
Later the sync shows the message that the Attachement upload has failed. No error message in the Cloud-Server.
I can't find the ID in the json on the Server. Neither of the Attachment nor the Task (the Task-ID isn't in the debug log?)
I didn't add any attachment on the mobile device and cant find any attachment in the inbox or Focus Tab
🔄 Reproduction Steps
- trying to trigger a sync
✅ Expected result
sync without error
