Understood (I had forgotten that). I suspect since the OS is no longer supported, you are stuck. Might be time for a new phone.No windows phone receives updates.
Good luck. You may not have much of an option if accessing those particular apps is required.I'm hoping a windows expert/tinkerer will have the answer. Nearly all apps have been disabled and the windows store which is where I'd expect to find alternative apps. The battery is still good on the phone so don't want to buy an android phone.
