Welcome in the wrong Microsoft club
If by club you mean this site, then this is actually the best 'club' to be in if you're looking for an answer.
If you mean Microsoft as a whole is the wrong club, then you're not helping anyone here that's looking for answers. After all, this site is called "answers".
Back ontopic. Am installing the second app update through my regular dataconnection right now, will keep you guys posted.
In case it makes any difference, before I did my last successful app update install I:
- cancelled (not pause) all downloads that had been started (in other words: cleared the "downloads" screen)
- disabled WiFi, NFC, Bluetooth etc., all except the basic data connection
- rebooted the Phone (keep the power button pressed for a few seconds until it asks to slide down to turn it off, then do so and start it again)
all previously disabled services should still be disabled when it reboots
- entered my sim password
- went immediately to the store and started only 1 download
- wait for it, takes much longer without WiFi
- switched to this site a couple of times and loaded a few pages (that didn't interfere with a successful download)
voila, it installed
