Hi, @Unti, Sean
Can you provide more information so that I can troubleshoot accurately?
- Can you provide a screenshot of the error?
- What is your device?
Judging by your current description, it is possible that your device is still managed by the old company, and you can try it Remove your iOS device from Intune | Microsoft Learn
More information can be found Unable to install new work email/tools due to previous employer device management - Microsoft Q&A
For better troubleshooting, I will add "Intune" tag for you.
