Screen Mirroring App - TV Cast

Just bought it, did not know the price, got a receipt from Apple the next day It starts mirroring and then fails. Going to notify my bank and dispute the purchase

This never picks up my LG smart tv or LG smart blu ray player. It searches and searches for 20 minutes and nothing!! I have followed all directions, restarted my phone, restarted the tv and blu ray player and nothing seems to work correctly with this app.

I hoped to be able to watch shows from my CBS app on my iPad on my TV. I immediately regret the purchase and want my money back. The lag was horrible and the audio never caught up with the picture. So frustrating to watch.
