Remove iPad as Speaker Option
I briefly purchased an iPad which was linked to my Apple ID. I reset the iPad to factory settings and returned the device to the store. Afterwards, I went under my Apple ID and removed the iPad as one of my devices. However, the iPad is still showing as a speaker option on my iPhone. I have searched the forum and it is advised to go to Settings > Phone > Call on Other Devices > [Remove the iPad {Disable it}] but that option is not visible in Settings. I do not have the iPad anymore and I only have my iPhone by which to make updates to my Apple ID. How can I resolve this?
iPhone 11 Pro, iOS 14
