Yep, that's good confirmation. So does this seem like a single-body anomaly or a signal that LA-EA4 adapters might be unable to autofocus screw-drive A-mount lenses on any future E-mount bodies?

I checked around a little in Sony Help Guides:

On FF bodys the LA-EA5 works on the A7RIV and on the A1 with screw drive lenses.

The LA-EA4 works on the A7RIV with screw drive lenses.

The LA-EA4 does not work on the A7SIII nor on the A1 with screw drive lenses.

The LA-EA4 works on basically all "old menu" bodys with screw drive lenses.

My own guess is that Sony removed (didn't port) support for the LA-EA4 to the new menu system firmware.

On bodys with the old menu system Sony added support for the LA-EA5 only on the A7RIV (and the A6600 APS-C body).

Why that is we can only speculate, but my guess is that they from now on on bodys with the new menu system will support the LA-EA5 but not the LA-EA4.
(the A7SIII don't at the moment support the LA-EA5 so that is an anomaly).

Since Sony A-mount bodys at the last years where made up on two "premium" bodys, the A77II for APS-C and the A99II for FF I guess that Sony thinks that the A6600 and A7RIV would make a reasonable upgrade for those who wants to go over to E-mount and keep A-mount compatibility. (Yes I know that they also had the budget A68 body on A-mount and for that there is no E-mount equivalent except the more premium A6600).
