Everyone left, am I forced into a vs AI game now?

Hi,

In short, after begining there quickly were just 2 other people besides me left. Soon there were only my neighbour and I, and now that I won our war, he left too. Am I forced to play vs AI now?
I have read that you can claim victory in such a case in the leaderboard section, but I only have the conciede button there.
Was kinda looking forward for that win, but now I am forcing myself to even log in.

Yeah, i think you need to have a star lead in order to “claim victory”. So you may need to battle the AI just enough to get ahead.
