I was using app inventor on mobile and then idk what happened but the things I select have like a black contour and in the blocks y can pick a block but I can't drop it, it will follow my finger always and I can't work it only happens with this account so I think I activated something
- If you are on Android, go to Settings > Accessibility and see if anything like Touch & Hold Delay or “Interaction Control” is enabled.
- Also, log out of your account and try logging in from a different browser or device. If it works fine there, it might be a weird local browser or device setting, not your App Inventor account itself.
