Very interesting.
Do I understand this correctly: the app fetches new posts on my Home timeline at the given intervall and stores these for up to 7 days --- without limit on the number of posts?
That is, via the cache the usual limit of max 400 posts in Home effectively no longer applies? If so, this is remarkable.
(The 400 limit is of course a major constraint for users who follow more than ~200 accounts.)
Thanks for all your work!
