Dealing with paycheque sync errors isn't the outcome I'd want for you to have. It's vital you're able to reap the amazing benefits of the features offered in QuickBooks and I'll be happy to help.
Based on what you've described, I'd like to start off by troubleshooting this issue to determine if it's a browser-related issue. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead. Try this out and let me know what happens.
I'll be one message away in case you need further assistance.
