The app that has been published about a month ago works fine in the latest 4k stick but there are some problems with Gen 2 stick.
1. Some UI issues (Text which is set to white appears red in Gen 2)
2. The app is extremely slow in FireTv stick Gen 2 as compared to 4K stick.
Along with this it would be much helpful if I get some insights on this well.
The icons looks perfectly fine in a 43 inch TV screen which has 4K stick but the same icon looks much bigger in a 32 inch TV screen with 4K Stick.
I have my drawables placed in drawable - xhdpi folder as mentioned in the guidance.
