A question was asked on the HCL support forum ( https://bit.ly/3a2hiWt ) because after upgrading Traveler to V11 just calendar entries have not been synced to Android devices.

The cause has been located and will be fixed like mentioned as answer:

We have determined the cause of this issue and have a fix for it in the HCL Verse Android Google Play Store beta slot. We are beginning the production deployment of the fix via the Google PlayStore at this time which should complete by Wed Jan 15th. This issue can affect Verse Android client apps with versions from 10.0.11->10.0.13 and is fixed in the 11.0.0 version (202001092238) of the app.

If a single user is experiencing this issue, the simplest solution is to have them open the Verse App on their device and click the overflow menu in the upper right hand corner of the UI and select Tools->Replace Data and select “Mail and Calendar”. Once the Replace Data is complete, the issue will be resolved. For larger sets of users the suggestion above using “traveler reset” can be used.
