Hi sorry for not responding sooner.
I have reactivated and solved the issue, but its still a bug that you could maybe resolve in next release. The previews of my gifs aren’t being created for some reason. It makes the file but it remains an invalid file in the Media section.
I resolved this by just making my own preview of the gif, saving it as the same file name in MS Paint then uploading it and deleting the invalid previous tmp file. It then worked fine
Thanks for the support, keep up the good work!
