Upgraded yesterday, I only use a small amount of features (files, memories, calendar, tasks). It sucks that tasks isn't compatible yet (but I mostly use DAVx⁵/Tasks.org as front-end), and it sucks that the landing page still pulls close to 20MB or so, but besides that, nothing to report one way or another.
Is Memories working for you after the 34 update? I remember it took a long time for the community to update Memories to work with 33, and that experience has me holding off on updating to 34 with the hope that app updates come quickly.
