On activity resume .fit file wrong

Bugs and Support
#1

When an activity is resumed (e.g. after a bluetooth disruption requiring a zwift restart), only the activity from before the resume is saved in the .fit-file. The activity after the resume will not get a new .fit-file for both parts of the activity but instead only get the partial activity before the resume.

My activity feed shows this:
before bluetooth disconnect: activity 1088455942434996224
after bluetooth disconnect: activity 1088447533862092800

The .fit for both activities is the same, the one from before the disconnect (8km instead of 58).

Any ideas on how to resolve this?

#2

After some more investigation, I saw that there are two .fit-files on my android device for this activity, one from before the resume and one after:
2022-05-27-16-27-56.fit
2022-05-27-16-44-09.fit

The .fit -file after resume seems to be invalid (size is only 584 bytes), the ride data wasn’t saved in the .fit-data for some reason.
