mobile subeta still shows my old v3 ha but since i don't have a ga anymore some items are missing and it looks super awkward ; - ; is there a way to change my v3 ha still?

I don't think there is. Have you converted your avatar to the new system yet? There's a link to do that on the front page of the wardrobe. If that works, you should be able to edit your HA in the existing version of the wardrobe.

yup i converted it and 3.5 works super well, just wish i could also edit the ha that shows on mobile xD right now this is what mobile subeta looks like for me

Ah, well maybe the mobile version is cached differently or something? I see a different HA on my laptop that I'm assuming is the correct one.

Yeah, mobile (which I use on my tablet) and the gift center seem to both use v3 HAs. It annoys me. :/
