Bluetooth alerts don't appear anymore on my Forerunner 235

Good day, it looks like since Apple moved to iOS 13 on my Forerunner 235 no Bluetooth alerts appear anymore. Mails and Whatsapp messages and other messages received on my iPhone SE aren't showing anymore as an alert on my Forerunner 235. They can be retrieved as notifications though but that's an extra step. Previously you would get an alert/pop-up on the watch as they were coming in on the iPhone. Do others have the same issue or is it just a setting I'm missing on my Forerunner 235 or in Garmin Connect?

Thanks in advance!
