IB Gateway 10.19.1c fails to load AUDUSD

[jeronymite]

With NT 8.1.1.1, I noticed just today that the IB Gateway 10.19.1c fails to load AUDUSD (although it successfully loads EURUSD and other currencies) with the error "Your API version does not support fractional size rules. Please upgrade to a minimum version 163". I have not tried it on 8.0.27.1, but it is probably the same there (see below) and so not specific to the new version.

It seems to be only AUDUSD and that's corroborated here: https://groups.io/g/twsapi/topic/95782811

The implication is, apparently, that a later version of the IB Gateway is required, with something beyond 10.21.0w (beta) being needed to be able to handle the code changes applied within IB.

NT Support, what is the situation, please?

Thanks.
