I was able to upload videos into data collection with upload and submit buttons. I have attached the screenshot on how I did that.
But I cannot any videos any more since Jun 18 and only get the error.
I have contact the Wix support, but the only replies I got are "wix does not support user upload videos into data collection" although I had attached the steps and told them that I was be able to do that...
I still can upload videos to wix's "uploads" folder. I tried the same method to upload images and it works. I also duplicated the website and can upload videos in the new website. but wix support insists that the error is not because of running out of storage or video hours. So I realy don't how to solve it. Can any one help? Thank you.
