How to watch Amazon Prime on TV with Apple Lightning to HDMI Adapter?

I have an Apple lightning to hdmi adapter that is less than 1 year old. Lately I am not able to view Amazon Prime programs when my phone is attached to my tv because of HDCP. I was able to watch Prime videos, but this changed about 2 months ago. I am in area without internet, and I use my unlimited phone data to watch movies. Is there anything that works?
