Review360 - Countless Issues

Hi,

Allow me to preface this with an apology as this whole situation has really irritated me and nothing is aimed at anyone.

I've been trying to upload a project to Review 360 at least 8 times so far and in every single one of those instances, the publish has failed and given me the most unhelpful of error messages:

"There was an error publishing your course to Review 360. Please check your internet connection and try again."

The project file is 178MB, contains video, audio, graphics, text, etc., however, I have uploaded a project file of 400MB to review 360 without seeing the error so prevalent.

Now my broadband connection is not fast, it's painfully slow, and like most other home broadband, the upload speed is even slower than the download speed (about 1mb or 2 on a good day) and I'm not aware of any throttling happening as this is a work provided mobile adapter. Said mobile adapter connects through O2 (UK network as I'm UK based).

Now, this "error message" is inherently unhelpful when the connection to the internet has _not_ dropped. So what could be causing the upload to be cancelled/dropped? Is it a server timeout issue because my connection is poor? If so, why do I not suffer similar occurrences when uploading to Microsoft Teams? Do Storyline project files retain somewhere in their code base when saved of any previous deleted content and that is causing issues? If project files do retain info like that, why? What purpose does it provide particularly when said project file is then saved under a different name/version? 

And before anyone suggest it, there is literally nothing I can do about my broadband situation because of where I am currently living.

So, if you've managed to get through all of that, is there anything worth trying that might help with the success of uploading to Review 360 without Storyline giving me that error message?

(Also my home broadband is in use by my other half for work and I cannot be slowing down her entire workflow by trying to upload something - seriously, it just cripples the connection down to dial-up speeds if not slower).

Regards,

Sam
