64 hex digit wifi WPA-PSK passwords not accepted by IOS App

From wikipedia: WPA-Personal Also referred to as *WPA-PSK* ([pre-shared key] mode, this is designed for home and small office networks and doesn't require an authentication server. Each wireless network device encrypts the network traffic by deriving its 128-bit encryption key from a 256-bit shared key. *This key may be entered either as a string of 64 hexadecimal digits*, or as a passphrase (https://en.wikipedia.org/wiki/Passphrase) *of 8 to 63* printable ASCII characters. So I went to my trusty ios ring app and asked to connect wifi to my wired ring doorbell. I paste in my 64 hex digit password and the "connect" button stays grey. If I delete one character (hence 63 characters) the connect button turns blue. Hence the app refuses to allow me to enter a perfectly viable 64 hex digit password (that most but not all apps think is fine). Now I am sure I am the ONLY person left on the planet using something other than a WAP passphrase. But it would be nice if the app would allow at least the basic specification of 8-63 characters or 64 hex digits. I did look to see if the ring doorbell offered up a web page to self configure without the app and perhaps without the 63 character limit - I did not find one. So I connected my doorbell to the backup WAP (the one I still have to have which uses MAC address authentication + password). It connected it works - but I have this problem with all of the amazon echo devices too - so virtually everything video ends up using that less capable access point. Doctor it hurts when I use a 64 hex digit WAP-PSK password - well then don't do that. Yes I know.
