I have multiple games checked off in my collection as "Now Playing", however they don't appear in the "Now Playing" section of my profile. I have them checked off both in the actual check-box and as the blue play icon. Am I missing something? Thank you.

The Now Playing section on the Profile page only shows active playthroughs. I've considered dropping the Now Playing checkbox altogether on collection entries since it was added long before playthroughs were as "meaty" as they are now. There's a help icon on the Profile page as a reminder.

In that case, how do I start an "active playthrough?" I don't see any toggle or option for it in any menu I've seen.

In the top menu, go to Playthroughs->My Playthroughs. From there you add a new playthrough for each game your playing, and can use all the features moho has created for playthroughs.

Ah, I see. I figured it out. Thanks a ton!

the playthrough thing is cool, nice way to keep a log and notes of what you're doing in game. confusing that it shows up as 'now playing' in the profile though. perhaps it should be called 'playthrough log or journal' instead? i don't know how many games i marked as 'now playing' trying to get it to show up before finding this thread.
