[Android] Chain validation failed (example app)

[ivanesi]

Example app works as expected on iOS, but on android I got Chain validation failed and see black background instead of map.

https://demotiles.maplibre.org/style.json is available and downloadable

Can you access the style file from the android phone's browser?

Could this be related to a wrong system time on the android phone?
