The 9.2.0 release implemented security improvements across the Roubler platform.
Previously, it was possible for an employee who is a member of a custom permission group to access the Roubler App without having explicit permission to view their own employee profile. The security improvements in 9.2.0 will now require the 'View own employee profile' permission to be granted to custom permission groups, this will ensure employee's have permission to view their own profile.
If employee's are reporting issues logging into their mobile app, please ask your Administrator review custom permissions and ensure the 'View own employee profile' option is checked for custom permission groups.
