Thanks for reaching out riz176,
It sounds like you're having trouble removing or updating a particular app. We can help.
From the way you describe the situation and the steps you've tried to resolve it, this could be an issue with a mobile device management profile. Usually these are seen on devices owned by a business or school, and they restrict what can be installed or removed from the device. The article, Intro to mobile device management profiles shows how to remove profiles, if possible, here:
Profile removal
How you remove profiles depends on how they were installed. The following sequence indicates how a profile can be removed:
1. All profiles can be removed by wiping the device of all data.
2. If the device was enrolled in MDM using Apple School Manager, Apple Business Manager, or Apple Business Essentials, the administrator can choose whether the enrollment profile can be removed by the user or whether it can be removed only by the MDM server itself.
3. If the profile is installed by an MDM solution, it can be removed by that specific MDM solution or by the user unenrolling from MDM by removing the enrollment configuration profile.
4. If the profile is installed on a supervised device using Apple Configurator, that supervising instance of Apple Configurator can remove the profile.
5. If the profile is installed on a supervised device manually or using Apple Configurator and the profile has a removal password payload, the user must enter the removal password to remove the profile.
6. All other profiles can be removed by the user.
An account installed by a configuration profile can be removed by removing the profile. A Microsoft Exchange ActiveSync account, including one installed using a configuration profile, can be removed by the Microsoft Exchange Server by issuing the account-only remote wipe command.
If your device is not managed by device management, you can Contact Apple for support and service as your next step.
Hope that helps.
Take care.
