Only thing with stremio is that the tv app has been crashing a lot recently-- I moved over to Nuvio (which can import stremio addons and watch history) and am very impressed with it so far!
Just english thumb key with symbols for me. There is a layout with a compose key to make accents like you would on an international keyboard (compose+a+`) or (compose+s+s), but I don’t use it personally
Also fan of thumb key. so easy without looking
sudo topgrade for me, it just does it all
Stremio has been awful for me recently on android tv. I looked into nuvio as a replacement (can use stremio addons and import your libraries and stuff, has some other nice features like skipping anime intros) as well as downgrading stremio to version 1.8.4 (use apkmirror or something and a universal installer for the app bundle). Both ways seem to be working well.
Been liking Carimara Beneath the Forlorn Limbs, Creature Kitchen, Eclipsium, and Northern Journey! Odd ones for sure but they are neat, short experiences.
