Okay. So the hide button is most likely broke.
It isn't. It works perfectly fine here on several browsers (computer and mobile).
You must have a browser extension that blocks/prevents that feature from properly working.
Try to log in private/incognito mode and whitelist poal.co in your adblock or any similar extension.
I use Brave browser and no extension. Runs https and standard default.
Check your browser's console for warnings or errors when you try to hide a post.
Just tried it again and again, it works flawlessly.
