Unable to delete multiple devices with generic names in intune app selective wipe.

@Kent CHEN Thanks for posting in our Q&A.

For Q1: Before you do this action, it is suggested to check if there are duplicate devices under Devices > All devices in intune portal. If yes, please check if duplicate devices' "Managed by" both shows "intune".

For Q2: It depends on if they are actually checking in. If the device isn’t actively being used, the selective wipe may not occur until the next time the app opens.

For Q3: It is not supported to rename BYOD devices in intune.

Generally, it is suggested to name your BYOD devices before enrolling to intune.

Hope it will help.
