Iwas notified that I had leveled up to level two. How do you check on your level or leveling progress? Like in other games it usually has a level and then the xp bar below it.
It must have said that one of your dragons leveled up, because those are the only things you can level up at the moment. You can check the levels of all your dragons by opening up your in-game menu and selecting "Dragons".
and your specific player level is actually just the level of your Town Hall (that castle-like building in your city that you upgrade.) you can see it as a number near the building or if you view your city from the realm you'll see a number in a circle next to your city. That's your Town Hall level. But Beta is right, the notification you got was one of your dragons most likely you hit monsters or returned from gathering and forgot or closed the game while they were still out and got the notification when you came back on.
