Playstore certification has no effect on getting system updates to be honest. So it definitely affects some apps relying on system integrity like Android Pay, it won't work if device is uncertified. Presuming guys at the service center did not root your device it might be one of the following: 1) issues with play store cache after service; 2) you have apps installed from apk downloaded from other sources other than play store. You can force stop & disable google play service, then clear its data and cache, enable service.
dear user 1509445273356
If your device is uncertified, Google doesn’t have a record of the Android compatibility test results.
Please keep in mind that:
Uncertified devices may not be secure.Uncertified devices may not get Android system updates, or app updates.Google apps on uncertified devices aren't licensed and may not be real Google apps.Apps and features on uncertified devices may not work correctly.Data on uncertified devices may not back up securely.
it is clearly mentioned in google help
