issue with Plezy, Plex featured cards on fire stick 4k max

awesome launcher seems very promising.
I installed it just now to give it a shot and I like it. However I noticed that it's not playing nicely with both Plex and Plezy " a plex client" apps. when on the top row, the featured "watch next" cards fail to load the episode/movie thumbnails for some reason. and only shows up as a black rectangle with the movie/episode title.

I'm seeing alot of setup here on this reddit where Plex watch next seems to be working just fine so i'm wondering if this has anything to do with the fact that im running the app on a fire stick 4k max !?
that being said, projectivy seems to be working fine and is able to pull watch next info fully from Plezy with no problems.

on a side note. can the featured cards size be changed to poster size 2:3 instead of the current square size 1:1 " or is it 16:9 im not sure"
