Instinct 2 Solar: Too little memory?

Hi, 

I've got a Instinct 2 Solar and I totally like the overall package, but there are a few quircks.

I installed the Komoot App, a Datafield widget, and 4 Watch faces. Now I am too low in memory to install any more watch faces. At this time I am just playing around, I do not really "need" so many watch faces, but I like experimenting, and I feel a bit dissatisfied with the existing ones. 

How do you guys use these features? What's your usage und experiance?

Cheers,

Chris
