As far as I can tell, the "Check for inconsistent translations" function/option is missing altogether from the QA Checker in Trados Team (see screenshots below).
This function cannot be "added in" in Trados Studio because verification settings for cloud projects are read-only in Trados Studio.
Please, please make restoring this functionality a top priority, as this is an incredibly helpful tool that we have come to rely on over the years - especially when multiple translators are working on files in one project or when one translator is working on a large and complex text with multiple repetitions.
