    It might not be a bug, it it is unexpected behavior. And should maybe be in the docs for
    IDropHandler

    I can't find any issue related to IDropHandler and IPointerDownHandler in the Public Issue Tracker (1, 2).

    If you're able to reproduce this issue, please submit a bug-report as described in this document:
    https://unity3d.com/unity/qa/bug-reporting

    It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

    After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

    well I had the same $%#$%$ issue, I was searching for a long time, I updated my unity from 2019 to 2020 and I found then today after 4 days that they made this bug....

    Solution: I removed the IPointerDownHandler and that is all, my game is working again after that...
