I was testing how notifications from popular communication apps like Messenger, Signal, WhatsApp and Messages on iPhone work with Garmin. There seems to be no way to open incoming message by clicking on a popup window. There is also no way to clear notifications from notification bar on the device. I'd like my Garmin to remove notification from phone and notification bar once it is discarded or read so new ones won't mix with old ones.
As for a replying to people I guess it's impossible because of iOS limitations and there is no possibility to notify someone at home that I'm on my way back?
