Prisoners won't use common room

[Vi]

Hi everyone. I just started playing this game yesterday and I've faced a lot of doubts or problems that I was able to solve by searching on internet, however I'm currently having this problem to which I'm not finding a suitable answer:

I built a Common Room for my prisoners and placed two TVs, four sofas, a pool table and five phone boots. I'm certain they can get through and all doors are built correctly cause Guards can get there If I direct them.
Despite everything, they are just not using it.

The answers I found said it's just broken and devs haven't fixed it, but they were all from a year ago.
Any comments on the matter would be really helpful.

Thanks!

Be sure that the route the inmates should take has no restriction (e.g. no staff only,...).

My cons don't use it a lot, but it happens, time to time (i.e. something around 5% of my prisonners per day).

Plus it's a requirement for the AA meeting.

Thanks for your comment on the subject, guys.

SOLUTION:
In case anyone has this same problem, this is what I found out:
The main thing is to have at least one hours in the regime designated as "Free time", otherwise they don't have time to use it, since in the time designated as "Yard" they only go to the yard. (This is what I wasn't doing right)
Apart from that, them using it is a rather random thing, as one of the folks here says. Some of them will use it and some won't, and it won't be all the time.
That was my outcome at least.

Again, thanks guys for helping out. :)
