JLinksz K960 'Device is not certified by Google'

[GertJL]

Good day Forum,

I have a JLinkSZ K960 tablet
Android 5 installed.

I recently side-installed an App 'DSTV Now'.  (from apkpure.com)
From time-to-time the App stops with error  'Device is not certified by Google'.
Looking at the PlayStore >> Settings >>> I see the message  'Device is not certified by Google'  related.

Is there anyway around this to 'fake' the Playstore setting such
 that the DSTV App wiill  'see'  it as  'certified'.

Thank you for your informed and valuable feedback.

Regards,
