Hi all,

After upgrading from 8.8.15 to 9.0, I am no longer able to bring the webmail up on an iphone, tried with safari and chrome but it just sits there at the loading screen but I notice the session keeps resetting (the blue status bar on the top when loading a page gets about 1/3 of the way then starts back at the left again and repeats indefinitely.

Looking for help to figure this out.
