Hey…hah I figured it out too except I did something different. See originally I was attempting to complete the tutorial in chrome and tried to copy the link and paste it in the brave address bar like it instructed but didn’t do anything, it just went to the Coinbase homepage. After searching Google 100 differenent ways I finally found a video on YouTube where the guy completed the whole tutorial in the brave browser and automatically got the reward. So that’s what I did, I opened brave then logged into Coinbase earn and completed the last step and it automatically credited the $7 in BAT.
That’s interesting that turning off the shield worked for you because I thought I tried that and didn’t work for me. Glad you figured it out though. I emailed support telling them the link forsnt work but they probably won’t do anything to fix it haha
