Hi Pete,
Thanks for thoroughly reporting the issue and for the helpdesk feedback. The GS-911 Diagnostics v2201.2 release which has the issue resolved is currently in BETA testing and will be deployed to all users once we are confident there are no new problems.
Regarding the legacy app: it is in fact not expiring in April 2022, and will remain usable as long as required. A "this version is more than one year old" pop-up can however be expected after that date to encourage users still using the legacy app to move to the new GS-911 Diagnostics variant.
Kind regards,
Francois
