apple store can not find macos Monterey
I am trying to update Catalina to Monterey on my Imac retina 5K, 27-inch, 2019 running Catalina 10.15.7. I opened Apple Store and clicked GET for macOS Monterey 12.6.1 but the "Finding Update" just keeps scrolling for 10 minutes now. Is there another way to update?
iMac 27″, macOS 10.15
