It has certainly been locked down a bit. This makes easily backing up all your data using some techniques harder/impossible.
I can't include podcasts in the backup I do via rsync via termux anymore, unless I switch to an app that uses a shared storage area instead, as termux can not longer read app directories only its own and shared storage. You have to rely on each app that used app-local storage to have its own backup method. Not that I really care from the podcast PoV, hence I've done nothing about it, but it is a sign of apps being better sandboxed at the filesystem level than they used to be.
That's doesn't make sense either - not an android iser or dev but shouldn't there be a system level backup interface. Even if its storing the app-local storage as an opaque blob with a label?
