I’m not officially diagnosed but I’m having a lot of trouble, being focused ans memorize things. Have you any methods, tools to help you backtracking what content content you’re watching or willing to in these platforms? Sometimes my browser remember the timestamp of a video, Sometimes it’s doesn’t.
What specifically are you hoping to remember. Just how far you were through the content? Which pieces of content you wanted to watch? Something else? All of the above?
I usually don’t have problems with platforms forgetting how far through a piece of content I am, but for remembering stuff I’m interested in, I usually use “watch later” playlists to save stuff I wanna watch, at least on YouTube
For shows I use JustWatch, which shows which shows/movies are available on what platforms. For books there’s goodreads and I think also a Foss/fediverse alternative
You may also wanna try grayjay which let’s you watch, and also save content from various video/streaming platforms (including yt and twitch) to a playlist for later viewing. Not sure if there’s a website or just an app, its pretty new
I’m having some trouble to remember if I’ve already seen a part of a long video. And also, sometimes I look at a thumbnail or title, and I’m telling : one day I’d like too see this, but there is something in the process which does I never do.
