I'm just starting to use Blackmagic Cloud and aim to use Presentations at least monthly if not more.
I figured out the whole 'not enough storage in the free account problem' myself, but am still having problems uploading a 2.5hr timeline to a presentation. I've uploaded several smaller 5min excerpts from the timeline in question so I know this works.
I can upload a 2.5hr timeline up to 99% or so and it tends to fail at that point. I did a diagnostic dump (see the Help menu in Resolve) and looking at the log it shows a network error on the BMC end, some sort of timeout. Looking at the log for earlier failures to finish and I see Cloudflare issues as well as BMC issues occurring.
Note that it may be my modest 40mbps upload speed that limits this, but the uploads are getting the full bandwidth and I shouldn't be seeing timeouts!
I'm REALLY looking forward to using Presentations, but need to be able to upload 2hr+ timelines to make this happen!
Update - Yep, the upload timeouts after about a hour or so and then fails. If you can upload faster and come in under that hour then you're OK. I did that by splitting the timeline, and both uploaded fine. You can see this happening in the diagnostics log I mentioned earlier, BTW.
I did notice that the same bitrate is used no matter the resolution of the timeline as the upload package was the same basic size whether the timeline was rendered as 2160p, 1080p or 720p. If you could choose a lower bitrate (or it lowered the bitrate with the lower resolutions automatically) then by simply lowering the timeline's resolution before rendering to a Presentation you might have a better chance of beating that hour or so timeout that seems to be the limiting factor.
But that is what is going on generally speaking (though I did see the occasional Cloudflare error in the log from earlier attempts), and the workaround is to split the timeline up so the upload is less than an hour.
But this needs to be fixed on Blackmagic's side, they just need to extend the timeout if it's possible or work around the problem in code, maybe by stopping and then restarting the upload newly before the timeout can occur.
