Run the following code (or similar code, making use of the “GetBlockedUserIds” core function) on the client:
local s, res = false, nil
repeat
s, res = xpcall(function()
return game:GetService("StarterGui"):GetCore("GetBlockedUserIds")
end, warn)
if not s then task.wait() end
until s
print("Blocked users:", res)
Notice that no blocked users are being returned via the GetCore method.
I have not had the chance to test other related GetCore events; they may also be affected by this issue.
Expected behavior
I expect the blocked UserIds defined under my account to be returned in the array.
To my knowledge, previously it would return all blocked UserIds regardless of whether they were in the current server; so this is still potentially an un-announced change in behaviour?
