Oh I think learning about Yoda's race is big, but yeah the whole universe spoiler crap was nonsense. It is why I didn't think it would be Gizmo Yoda until later. Never expected it to be Rey, because that was impossible. The tracking device hand me wondering what it could be though. The being had to be at least 50 something years old, which predates TPM by like 10 years at the point in which the Mando takes place. Which kind of put be on the track of Gizmo Yoda again. What else could it really be?
