IOS 10 update erased my iPhone Freedome licence
Freedome was installed in my iPhone 6 as part of multi-licence package.
I updated this iPhone to IOS 10 two days ago with the result that after the update Freedome did not recognize the licence and asked me to buy a new one. I tried activation by using the original licence password, but it was rejected "because I had used it already in the same iPhone". So Freedome is "off" in my iPhone is even though I have a valid licence.
The problem reminds me of a similar one I had short time ago when I replaced my old iPad and transferred its contents from the backup to the new one: the Freedome licence was lost during the process. The multi-licence could not be reactivated and the workable solution was to use an individual licence instead. For information: I updated also this iPad to IOS 10 and encountered no problems with the Freedome licence in the process.
Seems there are shortcomings in the multi-licence process, which do not affect single licences.
How can I reactivate my valid iPhone Freedome licence which was lost in during the IOS 10 update?
