Training status not updated - Forerunner 245 Music

My training status hasn't updated since I reset my Garmin Forerunner 245 Music in July this year. I have already tried the actions described in the FAQ, but so far I haven't been able to resolve the issue.
Has anyone else had a similar problem?

Here’s a photo:

  • You need a VO₂max value within the last two weeks, and it looks like you struggle to get an update - there are just two values since July, and are significantly lower than they used to be. One possible reason could be wrongly set Max HR value. Another one is that you do not use any external HRM chest strap. In your place, I would conduce a field Max HR test, set it manually in the settings, and disable the Max HR auto-detection. And I also highly encourage you to get a chest strap, if you do not have any yet. And if you have one, then conduce also the Self-Guide LTHR test found in the Training menu on your watch.

  • The maximum heart rate is set to 185, which makes sense for my age (35 years). What I find strange is that this issue started after I reset my watch. The workouts upload to Garmin Connect, but they don't count towards the training status and VO₂ max.

  • The workouts upload to Garmin Connect, but they don't count towards the training status and VO₂ max.

    In that case, I recommend to Remove and Add a Device From the Garmin Connect App | Garmin Customer Support, then record a new activity, and see whether it helped (it won't help with the past ones). If not, then have a look at the Troubleshooting guide for (some) data missing after syncing for more tips. 

  • You can't get an accurate max heart rate from your age. That formula usually gives you a too low max HR. That means that you should more easily reach 70% of max HR and get VO2 max values. So, too high max HR shouldn't be the issue here.

    Do you see VO2 max values on the watch? You should see a value directly after the workout in one of the summary screens (the one with recovery time).

    Are you doing activities that calculate VO2 max? Only outdoor running and walking calculate VO2 max values. For trail running the VO2 max calculation can be turned off. I assume you don't have a power meter on your bike since there are only running/walking VO2 max values in your graph.
