For the moment we do not plan to support Season of Discovery (SoD).
The issue is mainly time: we have our hands full maintaining the Dragonflight/retail and WotLK versions of the site. Adding another version, and one that changes frequently and has no extended PTR periods for us to prepare and test before they launch… probably would not be viable. We’ll keep an eye on how it plays out though – who knows, maybe something will change to make it more doable with our current workload.
For now be aware that neither the Classic nor WotLK premium addons will give you SoD support. If you have recently purchased either of these with the expectation that they would give you SoD support, please contact us via our contact form for a refund. Our next site update will have clear messaging on all of the purchase screens regarding SoD.
