I work with another person here who put in more effort on this. He used
a Configuration Profile and within that, created "web clips" to make the
necessary pages accessible with a tap since it appears that configuring
a homepage can only be done manua...
This is an old post and the answers seem to be few: Just looking at iOS
16.3 and didn't notice a setting to define it. The closest thing is Web
Clips but that is a little different.
#1 is of interest here as well. I suspect there's a plist configuration
profile but this seems like a common thing that more pre-configured
options would be available.
