It seems that works perfectly but I see the same amount of posts/ multimedia
I tried from archive and old tweets on true but nothing seems to change
It seems like I'm having this same issue. I tried without archive, then from archive, and then tried changing a few boolean values, with no apparent success. No errors returned, but it seems like it's only deleting 130 tweets (whereas yours says 883) out of thousands, and then I don't see any difference on the timeline. Every time I run the script it says it's out of 130, as if nothing it changing each time.
So, I got it to work, kind of. I attempted again not from archive, basically default settings, but with old tweets true. It didn't work, so I looked at the different IDs, and it looks like whereas authorization and uuid are constant, transaction id varies. So I attempted a bunch of the different transaction ids until it worked. The one that finally worked also worked with the archive, but I actually had a better result not doing it from the archive -- just re-running the script a bunch of times until they were all deleted.
