Keyboard repeat not working - MacBook Pro Catalina 10.15.5
Apologies if this may have been posted elsewhere but couldn't find it. Just got a new MacBook Pro, I've checked the keyboard settings in system preferences, key repeat is set to fast, delay is set to short, but no alpha characters will repeat at all when I hold them down. The only keys that repeat are punctuation, return,delete,spacebar, and arrow keys. Works fine on my old MacBook Air and the settings are exactly the same. Any help would be appreciated.
