Hello!
I've not seen such a list, but it would be interresting to see. Tho - android has so many combinations of versions together with various browsers that I think the list would'nt have much value - or atleast not for very long.
A few questions if you'd like to share and get some input for your troubleshooting..
Any specific combinations you've found that does and doesnt work?
What kind of onboarding? Just connection profiles or also certificates for eap-tls auth?
What kind of authentication? Local cp account, or AD?
Http or https? If https, is the ssl certificate public and certified for mobile devices?
I've often seen onboarding stop due to browser not accepting ssl certificate.
Also if you have redirects across networks from client net to clearpass net you can see browsers refusing to load the cp website.
