Google ends third-party app installs on older Fitbit Versa and Sense watches Nov. 28
Google announced that starting November 28, users of Fitbit Versa, Versa Lite, Versa 2/3/4, Sense, and Sense 2 smartwatches will no longer be able to install or update third-party apps and clocks. Existing third-party apps will keep working, but once removed they can't be reinstalled. Fitbit- and Google-made apps and clocks will remain supported.
