This apple account can't be used to make purchases ABM and intune

We have over 100 ios devices all managed with Intune MD and signed in with managed Apple ID's. all of our apps for IOS devices are purchased through ABM and assigned within Intune as a VPP app.

I have searched everywhere I can for a reason as to why this pop up keeps happening despite not having any apps installed on our devices that isn't provisioned through ABM and MDM. Any help would be appreciated.
