hi Sharla! thanks for posting this ))
if the 'implementing prompt engineering with azure openai service' module got moved. sometimes they reorganize stuff. https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/prompt-engineering, u might find what u need there.
search Microsoft Learn for 'azure openai labs'. their hands-on labs sometimes cover milestones before official courses update. found one last week that totally saved me %)
this might help in other tools too, when u hit dead ends like this, try searching the exact milestone name in quotes on github. engineers love sharing their learning paths.... checking community wikis – azure's fanbase documents EVERYTHING, sometimes better than official docs :)) looking for youtube creators who specialize in azure certs. they often make 'milestone walkthrough' vids before courses drop. worth looking into whether milestone 4 is brand new, could be their course team's still baking the content. happens more than u'd think )))
hope this unblocks u ;D
rgds,
Alex
