Tiller failing to update with Brave browser Mac OS

For anyone using the Brave browser on Mac OS … I’ve been using the Brave browser for the past several months because it uses less battery power than Chrome and because it works with most Chrome extensions. Up until a month ago, it worked well with Tiller.

Now it fails to load my Tiller data because it doesn’t complete “syncing offline changes.”
After failing, it returns this message, “Editing is temporarily unavailable. Check your Internet connection.”

My Internet connection is fine and other browsers work fine.

Since it works on other browsers, this isn’t an emergency. Any suggestions would be appreciated.

This issue might be related to the offline sync feature in Google Sheets. Here’s a guide that should help with turning that setting off.
