I have an iPhone SE 2020, a 2017 iMac and an iPad Pro, all of which have the latest versions of OS including Big Sur. The iPhone and iMac seem to be behaving “normally” and the iPad is behaving “normally” except for accessing the App Store. It is clearly making contact because the icon badge shows the number of apps available for update yet when I launch the App Store app it says “Cannot connect to App Store. This has happened for three days now. I have rebooted several times, carried out hard resets and tried three different networks, all to no avail. Everything else appears to be working normally and, as I mentioned, the iPhone and iMac access the App Store normally. I infer therefrom that the problem lies with or within the iPad. Any ideas what may be going on and how I can correct it? Thanks in advance.
