New sign-in alerts and welcome page appearing with 1Password for Safari (Safari version 18.3 beta)

I was having similar issues with the login notification emails and then random browser tabs would open saying welcome to 1Password. The random tabs seem to be related to the "Getting Started" tutorial. No matter how many times I tried to complete it, nothing appeared. Today, I opened the app, loaded a webpage, then opened the extension in Safari and clicked on the "one step to go." It loaded a blank tab that appeared to do nothing. After about a minute, I closed everything and tried to repeat the same set of steps and I have a "0" next to Start Here.

This seems to solve the random tab issue, but not the email issue.

This is on the latest iOS and iPadOS public betas (18.3).
