Anybody else get inconsistent results using the Online Session Steam Blueprints?

Whenever I seem to use the steam online sessions on my app id or the spacewar app id people seem to only sometimes be unable to join and sometimes they just completely can’t see the sessions showing up where as other times it works perfectly spot on. I have never had a problem joining or creating sessions on my app id but other people seem to have problems with it. Anybody know if this is related to me being the owner of the App ID and there’s some kind of restriction? Thanks alot

Nobody got any ideas how to fix this?
