FTP not updated in the App

Check out the document What Is the Functional Threshold Power Feature on My Garmin Device? and especially look at the section "Why Am I Not Getting an Updated FTP Estimate Reading for My Recorded Activity?" - perhaps it can help.

Hi Trux

Thanks you for your answer, I have checked the document you refer to and everything is well configurer on my Fenix 6. FTP auto calculation is enabled.

And what about the remaining conditions? 

• 95% of the average power for a 20-minute interval within the ride must be greater than the current FTP setting
• The average power for that interval of time must be greater than the previous 20-minute power record.

Also, do you have a powermeter connected to the Fenix?

The powermeter of my home-trainer is connected to my Fenix 6. All my cycling activities recorded up to now have power recorded in GC.

I have this issue since the Firmware 12.20 update of my Fenix.

I follow a training plan with Zwift for 12 weeks since begin of october with FTP improving de exercice.

As you can see on the screen capture there are no more FTP Data calculated since the 23rd of October, the day where I did the Firmware update.

If you suspect the firmware update, you should better post to the Fenix 6 forum instead of here, and ask if anyone else had the same problems after the update. If not, then it is probably just a coincidence.

You should also try restating the watch, if you did not do it since the update. It is always good precaution, to restart the watch after the update. The Master Reset would be another possibility, but that is more aggressive, and it would delete all your settings, and customizations, as well as VO₂max data.

Thanks a lot for your advice

Will try to restart my Fenix and if no improvement then will ask on the Firmware forum.

Hi Trux,
So I have called GARMIN customer service, and it seems not to be a problem from last firmware update.
All activities I did since the 20th of October have well the FTP data been recorded (in the FENIX 6 PRO and in the activities). However the FTP curve in GC App and Web version are not updated anymore since 20th of October. Customer service think it is more a GC issue, someone from Techincal service client shoudl call me back in coming days. I will keep my post update according to.

OK, thanks for the feedback. In that case, there is possibly on thing you could try (unless you already did) - follow the instructions from the support document Data is Missing from My Garmin Account After Syncing 

Was this ever resolved? I'm having the same issue. Missing historical FTP for 4 weeks and beyond yet every upload to GC has FTP readings all based off of vector V3 pedals. 

Unfortunately it is still not solved...
