Neo4j Browser Sync got very slow

I'm using Chrome as the Browser. But my browser got very slow after I signed in for Neo4j Browser Sync.

This is what I did: 1) I checked the box for Sign in/Register for Neo4j Browser Sync since I wanted to stored my favorite Cypher scripts. 2) Running pretty well for a hour or so, the Chrome began to become slower and slower. 3) I have to signed out and even clicked "clear local data" button. No help.

Can you please help me to resolve the issue?

I can access the Neo4j from a Firefox browser (without Neo4j Browser Sync) runs fine and fast.

Thanks,
Tao

Would it be too much to ask for Neo4j tech support to document this feature or simply declare it to be experimental/unworthy? I have two browsers on two computers: one features the browser sync cloud icon with a check mark (and it's green after login). The other features an empty space in the icon strip where that icon might be. Googling for information on the feature comes up with no useful information and here we are with unanswered messages dating back to 2019. Not cool Neo4j.
