When checking the compability of the lens sheet, the older a7RII is fully compatible (checkmarked), but the newer a7RIII is not, missing the third setting/switch for OSS and if choosen it will use the first setting only. How come?

Will there be an firmware uppgrade for the a7RIII to be fully comatible?

I really hope so as I made an order for this expensive lens and wold hate if this expensive combo would be crippled in that way.
