You're going to have to just relax. If, in fact, it is a new DRM, as we both think, it's going to take some time to fix. Depending on how complex they have made the DRM, there is no doubt, we will have to wait. No amount of complaining to Support will make it happen any faster. You know it has to be fixed and they know it has to be fixed, with time and hard work, it will be fixed. With the exception of HBO MAX (still waiting after 4 months), it seems to me, that the average time for them to figure it out lately is about 1 month. I could be wrong on the length of time ultimately because it is only based on the short amount of time I've used StreamFab.
On the bright side, look at the competition's situation. They've been promising, for some time, the imminent release of a new unnamed downloader. Of course, the name of the new downloader eventually leaked and it is for Peacock. If this is a DRM change then they are back to square one. Just think how these customers are going to feel after being promised a new downloader for so long and almost getting it. Disclaimer: this is all just speculation on my part at this time as I have no inside knowledge of what goes on over there.
