Is it just me?

I have had my Explore 2 for 6 months and I am really trying to love it but frankly I find it utterly frustrating. I use it almost exclusively for navigating using the Komoot app. I have turned off as much data as I can but these are the problems I keep encountering. Firstly the interface is unintuitive, if I want to switch between screens sometimes it's a swipe, sometimes it's an arrow at the top and sometimes it's an arrow at the bottom. I find it quite often displays random screens which I can't easily get out of. There s no simple way to simply get back to the home screen and start again. Sometimes when I have finished a ride and want to switch it off I get a message telling me it can't switch off because ConnectIQ is open and that I have to close it first. I rarely use ConnectIQ (so I don't launch it) but I do use the Garmin Connect app which maybe it is referring to but even when I close it on my phone I still can't switch off the Explore2 so eventually it runs out of battery. There are a lot of other little irritations and no doubt there are some clunky workaround or some small print in the manual that would address my issue but, honestly, all this stuff should be obvious. 

I live in a country where the sun shines almost all of the time so I always have to wear sunglasses. This makes the already dim screen extremely difficult to see. Yesterday the screen somehow managed to change the display brightness from 100% to 30% without any known input from me.

So is it just me or do others suffer from this pile of poo software? I am thinking of cutting my losses and have been looking at the Karoo 3, primarily for its brighter screen but would welcome any recommendations or otherwise.
