This is indeed a limitation Vue refs due to unwrapping, note it has been mentioned in a couple issues before. Moving to a discussion

Ah Ok, I think I saw some other previous similar issues, but they were for old syntax pinia stores. It seems like the solution for that was to use old syntax and simply cast as Ref as noted in #973 and it appears to work, is that the only workaround we have? If so, I'll probably rewrite it to use the old syntax instead of setup stores, do you also mind linking me to any issue/docs that contain information about this limitation? Would be great reference and learning for me, thanks! 😊
