Hi Alex,
I have checked everything, all settings is ok, but then I’m trying to connect to app store with mobile data a message appears: “cannot connect to app store”. I even try to change a sim card with other carrier, but I got the same problem. Other apps like youtube, facebook, safari works perfect with mobile data.
Some times then i turn of and on mobile data few times, after that it is possible to connect to app store for ~10 minnutes, after ~10 minutes I get the same message “cannot connect to app store”.
My college using the same mobile carrier with the same plan as I and he don’t have this problem.
Mobile data signal is very good (4G)
Before update to ios13 everything was ok.
