Agreed, something changed that made Slack usage across multiple devices much worse. Loading a channel tends to sputter as various state and messages load, messages I already read on different devices change state, it's pretty jarring to watch. The "unread messages" badge is often out of sync. E: if you reach out to support, they can reset stuck state for you. They were very helpful but didn't sound sure it would work.
