Okay. An update on the problem -- my apps store badge was showing 9 updates on hold in the chute.
First, I had started an thread on the IP4 forum that got merged into this one (and closed over there). Thanks to the mods for the redirect link.
Next, I tried all of the suggested steps by doing the step and then touching the apps badge to see if it would download and install updates.
Here's how it went:
- Reboot (turn off and back on) - nothing happened.
- Reset (hold home and on/off button until the screen blanks and the apple logo reappears) - nothing happened.
- Log out of apps store and log back in - nothing happened
- Set to Airplane mode -- something happened.
(Recall that after each approach I tried it to see if the apps would update.)
When I tried the Airplane mode suggestion I left it in Airplane mode for several minutes.
Then, when I took it out of Airplane mode and touched the apps badge it began buffering and the apps to be updated began to show in a list. Also, I noted it was at a 20% state of charge. So, I plugged it into the wall to assure it had adequate power for whatever was needed and left it running.
Everything updated and it is back to normal.
Thanks again to the several for the suggestions.
