3rd Gen iPad repeatedly loses iTunes Match after charging

It's been a while, but best I can remember, I performed a factory reset and used iTunes Match for a day or so before restoring my other apps from back-up. It seemed fine at first, but then, once again, I started receiving the messages that my subscription had expired. I gave up and just restored all the other apps. Over time, the problem seemed to occur less frequently, but in the past couple of weeks it has returned with a vengeance. I guess, the question is, how many times do I need to go through the reset and restore procedures? One of the Geniuses told me that there was an issue at one point with an earlier iOS and Match with regards to charging, but I have not been able to track down any info on that. Besides, my system is up to date.

I appreciate your interest and your feedback.

That's what I figured you'd say, Michael. Just need to psych myself up for the laborious process. Thanks for your help.

Sounds to me like it'll be "as bad as all that". :-\

Last time, I performed a factory reset. Then, after a couple of days, I began the tedious process of reinstalling my apps one by one, waiting to see if anything happened before proceeding with the next app. Michael, is that what you're suggesting I do again--but going directly back to the app store for each app instead of using my back-ups?

At the risk of sounding dumber than I probably am and wearing out your good will, what would your step by step procedure for this be?

Well, I guess, if push comes to shove. But it does sound eerily familiar to what I've done in the past. Not at all optimistic it'll hold for any length of time.

Gave it a try, Michael. So far, so good. Hope it holds. Thanks, again.

Figured I'd reply to you one more time, Michael. It's been over 3 weeks and I haven't lost iTunes Match even once. Thank you, again, for a surprisingly quick and easy solution.
