Hi I need some help. I have recently purchased a TomTom Touch. When I first did the setup I paired it to an iPhone 8 and all of the features worked fine. Now after the first charge, I am finding that the phone notifications for both calls and messages are not buzzing. The software is the latest version. Last night I re-paired the phone and the band and this seemed to fix the issue. However today I am having the problem again. This is the second TomTom product I have(I also have a Spark Cardio) where this feature does not work properly. Please advise a solution.
