I use Q1 with deovr 13.12.4. But as mentioned here - preview is working fine and paid content also can be viewed some days ago. Now only preview is worked. Then videos from deovr.com and from files fully viewable.
As a developer and QA I pretty know that all changes can be implemented in different ways. I don't know the root cause for such decision if it was, but it seems like your developers simply chose the easiest way again, which led to a broken Quest1 compatibility.
With such approach there is no guarantees that after couple of months users of Quest2 and other vr devices, will not find themselves in the same situation.
