Hi - I have been using 3 separate Iexpand flash drives for a few years now and they have generally worked pretty well with Iphones - my primary use is to encrypt files and use it only when necessary as opposed to storing files within an Iphone with a password.
But I cannot figure as to why but I am having a heap of trouble once I upgraded my Ios software to IOS 17. I have tried reformatting the flash drives, deleting the app, etc etc and nothing every works. But If I use the drive with an Iphone using IOS 16, that seems to be the trick.
Has anyone seen this?
