I can log in on the app and using my friends MAC that is not yet on 14.x.x. I also spent hours with Apple Support trying so many things, sage mode, private pbrowsing, new user account, even full reinstall of the OS. I also stopped by the apple stopped by the Apple Store and used one of their computers, all of which are updated to the latest OS, and I get the same error. Lastly, I have a tech friend of my to try logging in on his computer, ore upgrading the OS, which he was able to. He then upgrade to Sonoma and then was no longer able to login. Delta IT needs to fix/update their website code. Don't waste your time with anything on your computer, as the issues lies with DL's website and its compatibly with Apple's most recent OS.
