Podcast won't play on mobile safari
I have a podcast that I have been running for years with little to no issue. Two weeks ago the podcast just stopped playing in mobile Safari. It gives a play icon with a circle slash through it, like no plug-in. I didn't change anything with how I build the podcasts. I create them in Garageband share them with iTunes and use a content manager to upload them to my site. Can someone help me find a possible reason why this could be happening?
