Do you have a roof on your balcony? If so is there any way you can remove it to see if that helps? My outdoor sims get upset if there is a roof over their heads. I find it strange that they don't consider it outside on their deck but can grow their garden in the basement.

You can't place roofs on apartment lots, so, no.

You should post this in Answers HQ under bugs, that should get EA's attention and might lead to them fixing it in the future :)

This happened to me too, I think the balcony of the upstairs appartment counts as blocking the sun and thus the interaction.
It's not a very good design decision, a room without walls should be enough to tan but eh.
