Cannot download ANY app from Store. Error c101a006

Hi, I'm trying to download my apps before the store shutdown next month but I cannot download ANY app.

It shows an error with the code c101a006.

I was able to download any apps yesterday even without an email attached to the phone. Later I decided to restore the phone to the factory defaults before downloading the apps in anticipation to the Store being terminated. After the restore, I signed in with my email and for my surprise I can NOT download ANYTHING from the store.

There is some default app updates pending in the download section that also cannot be installed for the same reason, giving the same error code.

They start downloading but autocancels right after. When I tap then, they show the same error code.

I'm pretty sure the Store is not closed yet.

I already tried a lot of things that people suggest:

-Changing date+time to December 3rd of 2017

-Reset the phone (voldown+power)

-Restoring to defaults again

-Creating a new email

-Reflashed using Windows Device Recovery Tool

A lot of people already had problems with the Store not downloading apps, I also saw that some of them got this problem after factory resetting the phone just like me.

The problem in the link is not 1:1 but once I changed the date+time, I got the error above.

How are we supposed to download our apps before the Store shutdown in the next month, if we still have problems like this?

Can a representative take a look at these problems? Please.
