guild stash functionality

I already felt that last league, and this league still the same issue. So I'm guessing the devs either are not aware of it or did not care to do something about it but:

I own a guild and I also purchased several premium guild stash tabs.

And me as the guild owner, I feel like the transfer of items either from inventory to guild stash or vice versa, is extremely slowed down (laggy) compared to the regular stash that everyone has. And it's not just a thing that occasionally happens.

It happens every single time on every use.

And...the key combinations such as ctrl + right click to move the whole amount of a currency type for example, does not work for both ways (inventory to guild stash or guild stash to inventory) either.

Please look into that and fix it.
