I've been happily using Magic Trackpad 2 for exactly a year and a week (suspicious ;)) and today it started acting strange - I'm using only three gestures mainly (dictionary lookup, two finger scroll and pinch to zoom) and the pinch to zoom seems buggy - I'm not sure if that's the problem with the trackpad or the MacOS (10.12.6 - but I've been using that one for months now with no issues).
So in short - before I was able to pinch to zoom all the time, right now I have to pinch and nothing happens and then quickly pinch again to actually zoom. Most of the time it works 50% of the time. I have only one MacBook and I'm wondering if I can somehow check if it is really an issue with my Trackpad or maybe with the OS itself?
Also, a bonus question - what's the lifespan of Magic Trackpads? I've been looking everywhere but couldn't find anything. Can they last years? I'm especially interested in Magic Trackpad 2 as it's the one I'm using.
