I make unity browser games that are designed to work both on desktop browsers and mobile browsers.

I noticed that whenever a game is played on mobile the resolution gets noticeably lowered. The viewport resolution specified in itch project settings seems to have no impact, as the games on mobile always fill the whole page when pressing "play game".

The "mobile friendly" setting does warn you that the resolution will be decreased (which happens regardless of whether that option is ticked or not), but i'm wondering if there's a way to prevent that from happening, as my games should run with no issue at full-res on most modern phones.
