Level 20 Requirements for Level 16 Legendary?

Update: They sent me an email saying that they will reimburse the DNA and Coins I spent getting the Pteraquetzal which is nice. They haven’t sent to me in game yet but an email confirming their actions is awesome!

My DNA and coin came through this afternoon. Very happy with the response by @Ludia_Developers for fixing the issue so quickly, and the Ludia team for making this right for so many of us!
