Happy New Year 2026 !

Zwift (MacOS)
I started a Tempo into VO2 Max workout on 10:38 PM, Wednesday, December 31st, 2025 (CST).
The workout was completed 1 hour 6 minutes later ( 11:44 PM, Wednesday, December 31st, 2025 (CST) ).
This workout is the one that complete Rapha Festive 500. After I finished the cooldown, I clicked End Ride and Upload as usual. I was then prompted with the error message that there is a problem uploading the workout but it will be automatically uploaded once it’s ready (I cannot remember the exact phrase) with 2 options provided, the second option is Retry. I clicked Retryand the screen went back to the main Zwift page after that.
I figured that it would take a moment before I receive a mobile notification from Strava about this workout, as usual.
However, half an hour passed, there was still no workout synced up to my Strava. I checked on Zwift Companion app, and the last activity was the workout before this Tempo into VO2 Max workout.

Strava
I retrieved the workout file from Documents/Zwift/Activities/2025-12-31-22-37-41.fitand manually uploaded to Strava.
Everything looks fine, except:
• Calories 3 Cals
• Elevation Gains 3 ft

This is really frustrating, and I appreciate everyone in advance for this help.
