Silently changing a behavior, especially one that is in other web browsers, is a bit user-hostile and I understand the frustration.
On the other hand, privacy-wise this change is good, since it was likely storing the incognito tabs (browser state) in the app storage and was likely retrievable by forensics tools (ie: Cellebrite).
I’d rather have the browser state of incognito tabs stored in RAM at all time.
I feel like those affected are using incognito tabs as a way to separate their browsing history. Maybe a more convenient option would be the ability to run multiple browser sessions on mobile instead of falling back on the incognito mode as a workaround.
I usually stick to 1080p medium for movies and TV shows I want to rewatch, 720p for the stuff I’ll watch once.
For movies I try to stick to a 2-5GB filesize, and TV shows between 200-400MB per episode.
