It's frustrating not to be able to play audio or video messages on my brand new 2018 Passat from the Whatsapp App on my iPhone connected via bluetooth

All my other cars that are a lot older can will play them without any problems

After googling on the subject, I came across an article saying these audio/video msgs in whatsapp are now coded on OPUS, as opposed to AAC..:

Has anyone experienced this as well?

Is there a way to upgrade my Discover PRO Infotainment system with an OPUS coded?
