With the release of the new SwyxWare 12.10, the new 'Swyx Mobile' app has to be used. The previous app was renamed to 'Swyx Mobile 2019' in a previous release for better differentiation.
The new app can be downloaded from the Apple App Store.
In case that the app 'Swyx Mobile 2019' has already been used, the user should sign off before deleting the app to ensure a smooth transition. Afterwards, the new app 'Swyx Mobile' can be downloaded and the user can sign in.
