just got the Fenix 9 Pro - 47m, AMOLED, inReach (coming from a Fenix 8). During the transfer the apps attempted to transfer even though some were not compatible with the Fenix 9; these apps were WhatsApp and AccuWeather MinuteCast. In the Connect IQ app the apps are shown to be 'installed', but also show that they were incompatible with the device. There is an uninstall option, but when you try that nothing happens and it remains. On a side note, yesterday WhatsApp was in the, but today it's not there.
Obviously this doesn't affect the watch and maybe I'm being nick picking, but i guess the real question is how are these not available on the Fenix 9 yet? From my understand it's the same code base as the Fenix 8 and many other watches.
to the right of the app you want to remove/uninstall.
