I logged in r18 and got cookie.
It's all good now. Keepstreams $20 monthly will convert it to mp4. I have 4 videos saved so far.
If having trouble just Google keepstreams. When activate you have do it on the main vid part in settings. (If been deleted from r18 you won't be able to though)
Hope I helped everyone:)
(Definitely need a video tutorial of this man 😅)
