   Same symptom here: a WHOOP 5.0 / MG with no membership. History offload stopped working after the strap moved to firmware 50.43.2.0. History sync had been working before that update.

   • App: NOOP 12.3.9 (458), sideloaded, iOS 27.0.1, iPhone15,4
   • Strap: WHOOP 5.0 / MG, fw 50.43.2.0, no WHOOP membership
   • Live data still works. Standard HR and R-R arrive and are stored normally (insertedHRRows / insertedRRRows > 0 on every flush).
   • History never comes back. Each offload ends the same way:

     Backfill: session started — historical offload requested
     Backfill: session ended — reason=timeout outcome=nothing-banked
     

     This repeats every reconnect, then: Backfill: WHOOP 5/MG offload empty 2× — … backing off the bounce loop.
   • Also logged on every connect: fw gate: no version decoded — len=109 at93=0 expected=50 … hex[88..<101]=00000000000000000000000000. The hello reply looks zeroed where the version would sit.
   • Already tried: removed and re-added the strap, reinstalled the app, cleared the legacy R22 flags from the Test Centre (all cleared). No change.

   Has anyone on 50.43.x without a membership got history to offload again? Or is this the firmware refusing to serve history to a strap that has no membership certificate? I can share the full strap log if useful.

   Thanks, that's a useful data point. Two details would help tell the 50.43 update apart from the 45-day certificate counter:

   1. Roughly when did your membership end, and when did the strap install 50.43.2.0? Was history still offloading on the old firmware more than 45 days after the membership ended?
   2. In the strap log you offered, are there any lines with "Lock status" or "certificate counter"?

   Thanks! Answers:

   1. The membership ended about 6 months ago. I don't know exactly when the strap installed 50.43.2.0.
      History kept offloading normally for months after the membership ended, so well past 45 days.
      It only stopped recently, which lines up with the firmware moving to 50.43.2.0.
   2. No. I searched every strap log I have and none contain "Lock status" or "certificate counter".
      The only firmware lines are DIS: firmware=50.43.2.0 (standard profile, no bond required).

   Quick follow-up: nothing has changed on my side since 50.43.2.0. Every offload still ends with outcome=nothing-banked, and live HR and R-R still work fine.

   #2736 looks like the same symptom on a WHOOP 4.0 (fw 41.17.6.0) with an expired membership. So the cause may be the membership or certificate state rather than the 50.43 firmware itself.

   @ryanbr, do you have an idea what could make a strap refuse SEND_HISTORICAL_DATA like this? Is there anything I could capture to help? I can share a full strap log or run a Test Centre mode if that's useful. Thanks!
