Unable to customise blacklist

[NeighNeighNeigh]

Ive been having trouble with Keys on some webpages… so I want to use the blacklist to ignore such pages. Sadly the input fails after typing 1 character into the field. I am then unable to type any more characters.

Unfortunately, I wasn't able to reproduce your issue. Hopefully this issue fixes itself in the next update of Keys. Sorry 😭

Hmm, I updated and still having the issue. Here's a screen recording of me trying to add something to the blacklist.

My system:

Mac: iMac (Retina 5K, 27-inch, 2020)
OS: macOS Catalina 10.15.7 (19H15)
Safari: 14.0

Any updates on this? I have encountered exactly the same issue. Can only type one letter.

My system:
MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)
macOS Big Sur 11.4
Safari: 14.1.1 (16611.2.7.1.4)
