I was trying to watch a show on my z fold 3 using the Peacock app from the Google play store and it's not working. The app opens like it should, but when I click on the show, or anything for that matter, it just perpetually loads and nothing comes up. All other apps work fine.
You could also try uninstalling and reinstalling the app. If that doesn't work then uninstall the app, go on Google, and download the apk for it from a previous version
