Steam family sharing shows “buy” instead of “play”

So my friend let me try out Arma 3 by adding my account to family sharing. So he logged onto his account on my PC (Using TeamViewer) and added my account to family sharing, and while logged into his account, I downloaded Arma 3. The next morning, I logged out of his account, went onto mine and Arma 3 was there downloaded in my account but it had the “buy” symbol instead of play. I could see all of his other games but I couldn’t play Arma 3.
He also wasn’t playing anything at the time.
Any ideas?
Best Answer
Certain games are excluded from Steam family sharing. Arma 3 is one of them. Unfortunately, this means if you want to play Arma 3 you will either have to buy it, or play it while logged into your friend's account.
