Garmin Connect IQ - CONSTANT Issues

Why does the Garmin Connect IQ store always seem to have issues? I have the Garmin Viviactive 5. Brand New.

I can only download new watch faces from my watch.

Connect IQ doesn't want to install ANYTHING! 

Before this, I had the Garmin Fenix 6S. Had that watch for 4 years. Also, constant issues with Connect IQ with watch faces not downloading or updating.

Can they please once and for all, sort out Connect IQ to become a reliable app for these expensive watches.

And it's not the watch itself because I always make sure that my watch has the latest software installed.
