Okay, so Hive Keychain is indeed available in your browser. Seems like dGoal for some reason doesn't recognize it. I have some suspicions, will get back to you later today.

@autobodhi could you try it now? I modified slightly the checker function. It will try to load Keychain few times and if it does not success after 5 seconds, you will see the message.

Please make sure to open https://dgoal.app/login and hit Ctrl + R to hard refresh the page (to make sure you'll receive the latest build).

I am kinda guessing what could be happening for you. This is no trivial, of all places this is not something that I would expect to be buggy :D
