Yes, FoE on mobile has been implemented to become "aggravation-ware". Inno is attempting to break you down psychologically, with video ads (touch me! swipe me!, click me!) that flash similar to incidents, all day long unless you attend to them.
But wait! There's more!
Attending to your tavern must be done through a new tavern tab/screen that appears first, so you always get tempted to watch an advertisement for a basket of game non-value items (like 5% attack boost...) that last 4 hours - and you then can "do it again" for the same non-value items, 4 hours later (after 1 hour of mandatory cool down). 5 times a day - you can choose to give up your time, for non-value items!
To stop all of this this - you either:
1) say - to hell with it - and click the ads incessantly. Keep scratching their itch for them.
2) Buy their monthly package of extra value items, and the ads will stop - for 1 month (then begin again if you don't continue to pay each month...)
3) Move the game to your PC on a browser (as suggested by many others...)
4) Stay mobile game resolute but don't click - still attending to your game addiction each day. Takes fortitude, but many have it!
5) Find something else more friendly in the universe of city building games
