Hello.
I know that when we use the verb
to have in the meaning of possessing/owning, it is normally used in the present simple. E.g.
I have a new car. I have a blue pen. Even when I talk about the situation at the time of speaking.
And it is used in the present continuous (to talk about the present situation) when it is a linking verb -
I'm having lunch, call me later. vs.
I have lunch at 6 pm (each day).
When I want to say the sentence
It seems that he doesn't have/is not having problems with it today., what should I use? Please, do not talk about other options (He seems not to have/It seems he hasn't got etc.), just tell me if one of the tenses is more suitable or if only one of them is acceptable and if it is so, which one it is. Thank you very much.

Have a nice evening.
