When upgrading to the self service portal t0 4.0.0.7 some users may see this error message on the subscription view page of the portal.
To fix:
- Go to Work 365 > Administration > Admin Hub > General > Unit Mapping
- Update the unit mapping values for Hours and Days
- Save. If preferred this can then be unmapped as well just like it was before.
- Then clear the portal cache.
- This should resolve the issue.
