Hi, @Tessa15.
Welcome to the Roku Community!
We truly apologize for any frustration this situation may have caused you. This is not the experience we aim to provide, and we would like to help resolve the playback issue you are facing.
Let's start with the basics! Have you tried rebooting your router? If not, unplug your router from the power outlet and plug it back in after several seconds.
In addition, could you send us a photo of the exact behavior of the apps so we can investigate further? We would really appreciate it if you could provide one.
Looking forward to hearing back from you soon.
Thanks,
Emman
