Even with all addons off and only bagnon on i cant vieuw.
World of warcraft classic

I have the same issue, can't view bags from another character since last update (recently i guess last update)

BTW playing classic here.

Same, can't see inventory of other toons, as well as when I mouse over an item to see stock of other toons.
