solved Issue with not getting xp from watching anime episodes?

a lot of people are complaining they're not getting XP for watching anime, and I think I figured out why: i didnt get xp from episodes i watched on my second tab even tho it shows i completed them.
Say I'm watching Attack on Titan in one tab. I pause it, open another tab, and watch the new black clover eisode. It marks the black clover episodes as completed, but the XP doesn't go up at all.
What fixes it is making sure the anime you're watching is listed in the "Watching" section of your public profile, in my case it should be black clover season 2. That's the only one you'll get XP for.
