It's 2023 and the cross-platform user interface is the web, the rest has lost, and your devs and cross-platform community is on the web. Even a biased company like Microsoft don't seem to pretend anything else these days as they base their large scale (Office, Teams) apps on... YEP you guessed it, the web.
