After installing today's update (2018-10-30), the Other resources and services pane from the Dashboard has lost the settings for Google Translate, Microsoft Translator, Yandex and Deepl. Instead, MyMemory is ticked:
In CafeTran Espresso 2019's Preferences: Google Translate, Microsoft Translator, Yandex and Deepl are deactivated, MyMemory is activated.
There has been a change in Preference settings for MT services (to improve their (de)selection via the the Dashboard) so you might just need to reactive them in Preferences.
I'm happy to confirm your assumption.
