I can't listen to an entire episode

Hi,

When I play a podcast, it usually gets about 2/3 of the way through, and then it loops itself back to a random spot near the beginning of the episode, and replays the middle of the episode until the time reaches the end. I can almost never listen to an entire podcast! Once in a while there is no problem, but i would say this happens 75% of the time. This happens with all the podcasts I listen to, and both when i'm streaming and have downloaded them. Also, this has happened since i started listening to podcasts, and even was happening on my old phone, an iPhone 5, with earlier operating systems. Please let me know if you have a solution!

Thanks,

Garret
