Dear Luffy eli Hammond,
Although this behavior has not been officially confirmed, similar reports have recently appeared from multiple Copilot users.
As a workaround, please try installing the Copilot app directly from your device’s app store to see if that helps. If possible, could you also share the exact restriction message or a screenshot of what appears when you try to install the app?
In the meantime, please also submit feedback so the issue can be properly investigated by the relevant product team. If you can access Copilot on another device, select the three-dot menu in the upper-right corner, then select Send feedback > Report a problem. Include your operating system, browser, when the issue started, and a screenshot if possible.
Since this is a user-to-user forum, we cannot change this behavior or remove restrictions from your device. If the issue is related to the service itself, it will need to be investigated by the Copilot product team.
