Certain apps won't update - Error 404 "URL ... could not be found"
Yesterday, two apps that were listed in the Updates section of iTunes failed to update because of a 404 error; today, two more joined the list. Has anyone else had problems with certain apps not updating when they supposedly should? Most of the apps listed in the Updates section updated successfully, but I've never had any not update successfully, and now there are 4 over a span of two days:
Clock IT - Modern Nightstand Music Alarm
Grab for Instagram - Your Instagram Companion
Minesweeper Touch - Play by your finger
WorkFlowy
The text of the pop-up error message reads
The URL "http://<app link>" could not be found on the server.
When examining the Downloads listings, it reveals the error # as 404:
iMac, OS X El Capitan (10.11)
