Hi, no need to create a redundant thread, see the official thread:
OxygenOS 126.96.36.199 for the OnePlus 9R - OnePlus Community
If you read the first post, you will understand that the update is a random staged roll-out, so it could take up to 2 weeks for everyone to get it.
Depends on the region where you are, updates don't release at the same date for everyone.
Today I updated my one plus 9r. And my oxygen version changed.
It depends upon the region and date of purchase
New updates coming soon stay tune !!!!
Try to download Oxygen updater from the store so you can check if the phone has the latest update ☺️
It will be shown when need
