HI, here is my experience so far.

Have upgraded 2.1.2 and installed the latest version of WSJT-X 2.2.1, my result is I have no decode?

Not sure what is wrong as I have checked all my settings on the radio (FT991A) and all are as they should be.

Settings in WSJT-X are all ok and CAT test is ok.

Anyone any ideas, is there a glitch in 2.2.1?

Should also say I use a MacBook Pro late 2014 with IO's Catalina.

Also reloaded 2.1.2 and it works without any problems, so for now I'm sticking with 2.1.2
