Hi Experts

Show/Hide container has been disappeared when upgrading to April 2020. so i have import custom show/hide container.

However, i could not export the data if use the show/hide container. I don't want to use container instead of this container. Could anyone help?

Can anyone help ? I heard someone else encountering the same issue. Planning to upgrade ourselves and we want to avoid that we lose all the show/hide containers.

How can we be absolutely sure this doesn't happen?
