Same here.. Tried all the usual tricks from Apple... (you know, the one that telling you that the problem is in your side, not their..) sign in, sign out, reboot, hard reboot, re-sign out, re-sign in, check date and time, reset network, full reset, change country, accept term, re-change country, re-accept terms, cancel etc... etc... Nothing works...
For update apps, I was able to do it by uninstalling the outdated version and ask to re-install it after (did it for Apple Store app). It works.. no need to agree... But for new one... Nada, zero... just the vast emptiness of my disappointment with a zest of anger.... It seems it affect a lot of people...
I am snorting with derision and throwing my arms in the air, exhausted by their constant tomfoolery... :-)
