APX 320X management

Hey, i guess this is an mistake. Topic is about 320X. APX320 should work on both XG/SG.

"with more features in Central" That is not correct for all terms - for example you cannot create a SSID with the same name more than once in Central. e.G. for multiple sites with different settings. That's big missing feature for us compared to XG managed APs.

Is there a solution for UTM/XG so far? Or do anyone know a meaningful release date?

Management is still only possible via Central. There are some promo action to move the management to Central. Would recommend to talk to your local Sophos Partner about the possibilities.
