Yes the app block definitely renders in the theme customizer. No issues there at all.
App block is definitely in the loop logic:
However as mentioned, the app block doesn’t seem to be part of section.blocks, so the problem is higher up the chain that this.
I don’t have permissions to view Markets on the store. There’s no indication of multiple markets being set up but maybe that’s due to my permissions. I’ll contact the merchant about it though.
There’s only a small number of apps on the store and none seem to be performance optimizers.
