Send notifications to members greyed out

When creating an automation to send notifications to other members when someone leaves or arrives the step to notify the members are greyed out.

IF
This member isn’t at Home
[member name]

THEN
Add Action -> Notify Someone -> Send notification to members -> FIELDS ARE GREYED OUT.

What could be causing this?

Did you click on/touch the message field to enter the message you want to send?

Sorry, yes I did. It won’t let me type anything.

Android or iOS? What version of the OS?

It must be an iOS 14 issue. Tried on wifes phone and its ok

I have iOS14 beta and it works. Beta 3, let me install beta 4 and test
