Since tuesday garmin has disabled the synchronization of "third party" activities to third party platforms (So e.g. Zwift -> Garmin -> e.g. Runalyze).
This synchronization of third-party providers has also been possible "only" since the end of April 2020, but that after a year to declare a "bug" I find an unfortunate move by Garmin.
From a technical point of view, it would at least be understandable to take some load off of Garmin's systems, but that should really only be a trope on a hot stone.
What is your opinion about it?
