Calendar notifications not working on new Vivoactive 4s

It could be that you are using different calendar app than you enabled in the GC Mobile app notification settings. Compare the settings with your husband, and make sure you use the same calendar app, and in the same way as himself too. The functionality is not depending on the watch model. Only on the GC Moibile settings, and on the calendar app. 

Well, there must be some difference. Perhaps on the level of the Android system. It is certainly not because of the different model. If you do not trust me, and want to verify it, try temporaily linking your watch to husband's account to see whether it gets the Calendar notifications there or not.

Note: it is safer to perform the Master Reset on the watch before swapping the accounts (in both ways, to your husband's account, and then before switching back to yours), to avoid the mixup of user data.

Thanks, we'll see how it goes.

Ended up uninstalling Samsung Calendar and installing Google calendar and now notifications work perfectly.

Yes, that exactly why I wrote the following already in my first reply:

Thanks for your help.  Both of us were using the same calendar app and it still wouldn't work with my watch, hence changing it to Google.

Interesting. Perhaps your husband has the Samsung app linked to the Googe Calendar, so it transfers there all events automatically.
