it seems the android browsers aren't compatible with icloud.com to view photos. Some browsers give the error (this browser is not compatible) or simply display a broken view of the photos on icloud.com, still looking for the solution... I've tried the built in browser and downloaded Chrome, Firefox, and opera all do not work to view my apple photos on icloud.com from my android phone.
Chrome for android: error your browser is not currently supported
Firefox for android: error your browser is not currently supported
Opera for android: error your browser is not currently supported
built in browser for android(stock): shows page but unable to navigate my photos
