Store is still missing items for me, but I know this update doesn't say it's going to fix it.
Gris and Bulletkin are still missing for me, even though they were in rotation before and I didn't buy them. My store is all coming soon still.
I already raised with support when it was first an issue for me. 5.fun only fixed Alyx being missing for me.
Just relayed to another poster, but I'll definitely chase on this!
