Exposure is locked in afc on X-T4

Today I also updated my X-T4 from 1.22 to 1.23 and indeed, the bug is fixed.

Could you please test out what I`ve reported here[1]? It`s for X-T3, but as the same bug was present there, I guess the "fix" is the same, too.

In short - in AF-C mode, with "SHUTTER AF" set to ON (for AF-C) and "SHUTTER AE" set to OFF (for AF-C), on holding shutter half-pressed and pointing camera from light to dark scene (or vice versa), exposure change is delayed and rather slow (smooth), requiring you to wait a few seconds until the exposure gets to what it should be before you can take the shot.

On the contrary, in AF-S mode, with "SHUTTER AF" set to ON (for AF-S) and "SHUTTER AE" set to OFF (for AF-S/MF), on holding shutter half-pressed and pointing camera from light to dark scene (or vice versa), exposure change is rapid - as expected, and as it should be for AF-C mode, too, I would say, allowing one to take the shot immediately, without having to wait for exposure to slowly adapt.

So even the situation is now better for AF-C, where instead of not changing at all, even with "SHUTTER AE" set to OFF (for AF-C), the exposure now does change again, but it does so very (and unnecessarily?) slowly, for some weird reason...?

Yes Boogisha, my X-T3 (FW 4.12) behaves exactly as yours. There is a long delay in AF-C while the exposure slowly adjusts if I use your settings. There is no such delay with Shutter AF set to OFF.
