Ash incursions; What lvl do quests stop?

WoW Classic Season of Discovery

If i recall they use to stop at 50 but not sure if that has changed. I believe Feralas/Hinter incursions start at 48.

When to the Ash quests stop giving EXP?

thanks

I believe I was reading something akin to:

Duskwood was 25-34
Ashenvale was 38-45
Feralas/Hinterlands were 48-54.
