Today Garmin has released a new beta version 8.15 for Fenix 7 series and Epix Gen 2 smartwatches. Like the previous 8.13 beta updates, the new version also included added features and fixed bugs. Well, looks like in the process of squashing known bugs Garmin has added a few more. On the official Garmin forum, the company announced it has noticed two major bugs in the beta software. According to the official note, the new 8.15 version will interfere tracking of stress and sleep data.
It has requested users to not install this beta version until the company comes up with a fix. If you have already installed the new beta, then you should reboot your smartwatch to resume the stress and sleep tracking. Users can also revert to the previous public version if they want, but it will take them back to the 7.35 public version. Also, the backdating software will revert all the settings to the default settings.
Here is the official answer from the Garmin team about the latest known bugs.
Hello, Fēnix 7 and Epix customers,
We are now aware of a bug in the v8.15 update which can interfere with the tracking of stress and sleep data. Luckily, the tracking of this data will resume after a simple reboot of the watch (turning it off and turning it back on again.) If you have already installed the update, please perform this reboot of your watch to correct this problem.
If you would like to avoid this bug entirely, we recommend that you do not install the v8.15 update. If you have already installed this update, remember that you have the option to revert to the current public version of the software, v7.35. Please note that backdating software will revert your watch to default settings.
We apologize for the inconvenience, please know that we are working to resolve this issue as soon as possible.
