Looking for some mod levels answers

Ive been looking around have had no look find my any kind of answers so im here.

When you upload a map level then sometime down the road u update it do all players who have subscribed to the mod level automatically get the new version to their devices?

 

If they subscribe to the mod via the repo or in-game repo, then yes, but if they only download it, it won't update automatically

 

But they either need to enable automatic updates in their settings (no idea why it is off oin default) or press update mods in the mods manager to actually start downloading the update
