Hello,
This is an FYI for the ZQ team and community regarding a bug in the AWS File uploader plugin. This bug can be worked around, if you know how to do so.
The bug: For the file uploader element, if the element is hidden and then shown again, it no longer appears on screen and cannot be used. This includes if the element is inside a group or popup that is shown and hidden. This bug isn’t fixed by using the reset action, and occurs on both responsive engine types.
The catch and workaround: This bug only occurs if the element doesn’t have a border (or has a border of non-zero width). If you add a border, it works properly.
I have a test page demonstrating this issue which I can share with the Zeroqode team privately, if you reach out (I cannot share publicly due to it being tied to a proprietary app).
