I tried using Synapse to report this and have twice had my explanation erased for no apparent reason. It's way to sensitive to something, and after two tries, I'm giving up on Synapse.
I use 1P to login to my PNC Bank account. First, I go to https://www.pnc.com/en/personal-banking.html, where I have to fill in my user id. I type CMD-\ and 1P fills in the user id and I'm taken to another screen where I'm to fill in my password. I used to be able to just type CMD-\ there and my password would be filled in. Now that doesn't work, because the 1P menubar menu is still open and typing CMD-\ just succeeds in closing the menu. I have to type CMD-\ a second time to get 1P to fill in my password.
