I used to do this all the time on my DSLR cameras but can't seem to make it work on my mirrorless. Is this no longer an option in aperture priority and only works in manual mode?

I actually think I figured it out but with a caveat. If you go into "external speedlite control" you can scroll down to "slow synchro" and select 1/200-30, 1/200-1/60 or fixed at 1/200. 1/200 is the factory setting and it will always be 1/200 in Av mode regardless of ISO and if you have HSS on UNLESS you change it to 1/200-30 or 1/200-1/60. When you select one of those two options, it allows you to use HSS in Av BUT if you're ever in a darker environment with with a strobe on, it'll take your shutter speed all the way down to 30 seconds or 1/60th of a second vs keeping it at 1/200 all the time.

Yep. These are the settings I was just talking about in my previous post. Thanks.

By default this is set to Auto NOT fixed. So a setting has been changed inadvertently.
