Problems to upload (Patreon)

For some strange reason every time I try to upload very heavy files to Patreon. On the screen where the file is attached once it finishes uploading and it indicates me with a symbol of ok.

When I save the changes and then upload. The file disappears and nothing appears as an attachment ...

Then I upload the file again and it happens exactly the same ...

That's why every time this fails me what I do is upload it to Mega and then pass the link.

That's why I ask you every time you see that I upload a file and nothing appears to download. I ask you to wait a while longer than I surely am trying to upload it again even if it is on another server.

Sorry for the inconveniences. I'm going to try to see how to solve it.

Thanks for reading!!
