Option to flip up-down a Simulink block not available in 2020a

I tried to flip a Simulink Sum block (with +-) up-down but that option is not available in Simulink 2020a Home Edition. Has this been diabled? I can do the flip left-right, but there is no option for flip up-down?

You can show block name on top or bottom but there was never a up-down flip. If you want to change the position of the port, change the "List of signs" to be "++|"

Hi Fangjun, the option to 'Flip Block Name' not only flips the block name, but also any ports which are coming in at the top. The 'Enable' or 'Trigger' port of an enabled or triggered subsystem for example, will move from being at the top to the bottom.

Just an fyi.

@Jonas, I would say no up-down flip if you look at input ports. The reason for trigger port might be to avoid line corssing the block name.

Indeed. I think the implementation is good, because if the port ordering would flip as well it would be confusing with regards to port numbering.
