Hi, so I've been using Adobe Creative Cloud Express (previously Spark) for a long time and all of a sudden it no longer accepts my video files when creating videos? I always work with .mp4 files and have never had any issues before. In most cases, these are files generated by Adobe Premier Pro. I have even tried using Adobe Media Encoder to convert them to alternatives, but still get the same error message.
Apologies for the delay in getting back to you. It seems that the issue has resolved itself without me having to clear my cache or open an incognito browser window. Not sure what the reason for the error was, but I do know that my colleague was having the same issue with it at the same time.
Anyway, thank you for your help, if it happens again I will report back
I have tried your solutions of clearing cache/using incognito mode and I still cannot upload a video, even once converted. Spark worked so well, but CCE is useless if you cannot quickly import videos. Please advise.
