So i'm 60 turn into my Athens game, got a pop up saying the Ionian revolt is happening, proceeded to declare war on Persia and nothing happened. Few turns later and i still got nothing. According to this:

Starting in 500 BCE, Regions with at least one Hellenes ethnicity in coastal Asia Minor with less than 75 loyalty and less than 60 combat power of units may revolt, if not occupied by a Hellene nation. Once one revolts, others that satisfy the conditions will do so too, once. If Athens can go to war with the occupier(s), it will do so instantly. If it can go to war, the region goes to Athens, and the city immediately receives one Armored Hoplite, 150 money, 25 manpower and 25 metal for each region in revolt.

I should be getting a bunch of rewards when i go to war with the occupier (Persia in this case). But nothing has happened so far

Another thing is that it's been more than 10 turns since i got a mission. My last mission was to form the League of Delos but i failed it, only managing to capture Lesbos. After that there was no mission

I'm quite lost, how does the mechanic work? Can any experienced player help me?
