I’ve got the Home Assistant Companion App running on an older 7" Fire tablet. The app is on version 2023.1.1-full and it’s not loading a HACS custom element card on my Dashboard. The HACS front end plugin is in the www/community/mini-media-player/ folder and the Resources config in the dashboard has it pointing correctly to the /hacs/ folder and set as a module.
The card works fine on a Chrome browser on the tablet, as well as various browsers on other laptops and phones. It also works fine on the companion app on my phone, with the same version.
I’ve uninstalled and reinstalled the app on the tablet to make sure there was nothing cached, but no joy.
I’m at a loss of where to look or investigate to see why it might not be loading properly. All the other similar topics I can find are all around it either working on everything or nothing. This is only happening on this one device, which makes me think it’s something to do with either the tablet hardware or my config in the app, but there is nothing obvious.
The full error message is:
Custom element doesn't exist: mini-media-player.
type: custom:mini-media-player
Any ideas?
Thanks
EDIT: When debugging the network requests in the app there are a load of javascript errors and same site origin errors. When I check the same network requests but using the browser on the tablet everything seems to load fine. I would have expected the app to use the same browser engine as the actual browser (Chrome in this case). Is there a reason that the network requests would fail, and some of the javascript would fail to parse/run on the app, but runs fine on the browser on the same device?
