Due to Microsoft's issues on their services on 16.3.2021, functioning of CSM for Intune may have been altered. We are checking and fixing possible errors, but we also recommend our customers to contact our support, if they encounter any problems or anomalies in CSM for Intune.
The most likely problem that may occur is that deployments of new application versions will not appear on Intune in a normal schedule.
See Microsoft's tweet regarding the impact here.
