Notifications on Huawei Watch 2 don't vibrate

After installing Facer, the notifications stop working on my Huawei Watch 2. The little symbol still appears on the bottom of the screen and the emails and messages are there, but there is no more vibration or notification on the main screen when I receive a message or email. I have tried all of the options in notifications and reinstalled phone and watch, but with no success. The phone is a Huawei P30 Pro with Android 9.1. Any help is welcome. Thanks.
