Podcast controls showing on lock screen

I’ve been having the same issue, random podcast episode (the same exact one) keeps showing up on my locked screen. I deleted the podcast app, and it’s still showing! There’s obviously a huge glitch going on, and i don’t know how to get rid of it. I turned off Siri suggestions and still keeps showing.

You may want to turn off Siri Suggestions. Go to Settings > Siri & Search, then scroll down to Siri Suggestions, and uncheck the options you do not want.

Go into Settings, then select Control Center. In Control Center select Customize Controls. Turn off what you don't want, turn on what you do want.
