Heyooo! Just wanted to give an update: I once again reset my iPhone - but this time I did not restore from a backup - and it appears to be working for the time being. Figured this would be helpful for anyone else experiencing this problem if everything else fails. Appreciate your help PBK!

Yep - all correct😟 I find this super odd because it literally was working - and actually worked one single time (I thought it was fixed) in the midst of my struggle here - but has since reverted back to "Cannot connect to iTunes Store."

You are correct - I've uninstalled/re-installed directly from XCode (on 2 different devices that were both working at one point - 2 different Sandbox accounts attached under Settings > iTunes & App Store).

This same problem is now happening to me as well. Everything working fine earlier yesterday, but now being met with "Cannot connect to iTunes Store" in the console when tapping the purchase button for my item. I've tried creating new sandbox accounts, logging-in/out of iTunes (both real and sandbox account). Right now I'm restoring the phone so I'll report back if that does the trick. Update: Issue still occurring after restoring from iCloud 😟

This is happening for us now too. Everything was working fine earlier today (like... 2 hours ago) but now we're stuck waiting until this is fixed... Any ideas? Do I have to make another sandbox user (which in and of itself is a bit of a chore)?

Exact same problem here - newer account (about a day old - even that took well beyond the 48-hours it said it would take).
