I've noticed that ever since I upgraded to Mojave, 1Password can no longer autofill logins (or anything really) in Mojave's version of Safari Technology Preview. The browser has the 1Password browser extension installed but when I try to use it, I get the proper login preselected but asking it to fill results in nothing happening. Things do seem to work properly with the standard version of Safari but my workflow has me using Safari Technology Preview a lot and I'm trying to avoid running two browsers any more than I need to.
Thanks for any help that you can offer.
1Password Version: 7.2.5
