This is to inform that there is an issue in the Iqoo 9 pro with the widevine certification. Iqoo 9 pro had Widevine L1 certification,but now for a few months after an update , the certification for the Netflix, Amazon etc has been downgraded to L3.

Now the playback is only possible in SD. 

It is very annoying that the flagship device that supports all the hardware  that is required to stream the videos in the highest possible quality, can't even stream the HD contents. 

I would like to know whether anyone else is facing such issues with their device & is there  any reason for this downgrade and i would require a solution for this issue if there any.
