mzcommerce.jmssenderror_message and error 11111 while trying to download a app.(Minecraft PE)

This did it for me :

Sign out of your account in the store.

Sing in again.

Go in your account details on the store and re-enter you credit card information, validate.

(I also changed my Phone number ... but I do not think there is an incidance).

Et Voilà I was able to update all apps without any error message afterward.

Mine just started working again. I checked App Store, iPad, iPhone, and iTunes and no issues. Hopefully they have fixed it for everyone.

Today it's working also here in Italy, and according to another couple of threads in the forums they've eventually fixed their bug. I've reached the personal record of 75 app updates waiting to be downloaded and now they're flowing down the pipe.

Hooray. No response from Apple to my open support ticket and/or to the threads here in the discussion forums, but at least for me the problem resolved itself last night and continues to function fine. I had confirmed it working on my devices last night and confirmed iTunes operation this morning. It appears to have been iFixed.

Interestingly, even though this problem was clearly fixed a few days ago, I've just received another email from the support person who originally replied to my message to Apple Support:

"Hi YYYYY,

It's only me, XXXXX, from iTunes. I hope my email finds you well. I just wanted to send you a quick note to let you know that I haven't forgotten about you. Our engineers here at Apple are still working on a resolution to the error 11111 you encountered. As soon as I have additional information, I'll pass it along!

Many thanks for your continued patience and support - it's very much appreciated!

Sincerely,

XXXXX

iTunes Store Customer Support"

So maybe someone is still facing that problem, but luckily all updates work for me now.
