I didn't have this problem for over a year when bouncing off the ceiling, but now am getting underexposed images on everything I shoot.

Also, someone had mentioned that shooting at wide apertures causes this problem. I just tried using F4.5 and still encounter the same issue (ISO 100, F4.5, Shutter Speed 1/320 for HSS).

Obviously one first needs to check whether a flash exposure correction Ia being inadvertently applied.

Of course we don't know the lighting conditions in which you are shooting. However 100 ISO is very low for flash. In some tests I did with an A7R3, I think Sony's default ISO appeared to be 1600 in artificially-illuminated domestic rooms at night. See if a higher set value cures it, using aperture priority. I normally go for 400 - 800.
