Given the impossibility of controlling the iHost with a small screen I thought I’d try with an android-TV.
Tried with two different browsers and installed Tailscale on the TV to see if that’d help.
I suspect it is because the android-TV browsers are harder to get and less mainstream. The two Ive tried are BrowseHere and TVbro. I will have a look on the play store for something more common, but from memory android TV doesn’t have Furefox, Chrome or Safari.

Nope, nothing common is available for android-TV. Checked for Firefox, Chrome, Safari and Edge.
Any idea what works on android-TV?
