Has anyone else had a problem with connecting sensors since upgrading to version  12.30  I can no longer connect my Edge remote or Cadence sensors

    How did you roll back to the older software? I can't find how install 12.10 in Garmin Express.

    Istruzioni per l'installazione
    Collegare Edge Explore 820 al computer tramite il cavo USB.
    Scarica e decomprimi EdgeExplore820_1224Beta.zip. Posizionare il file GUPDATE.GCD nella cartella \ GARMIN della memoria interna del dispositivo.
    Scollegare il dispositivo dal computer, approvare l'aggiornamento su Edge e attendere il completamento dell'aggiornamento.

    **

    Se si desidera ripristinare l'ultimo software di rilascio pubblico, seguire i passaggi precedenti ma posizionare il file GUPDATE-1210.GCD nella cartella \ GARMIN. Rinominare il file in GUPDATE.GCD prima di disconnettere il dispositivo. NOTA: se si ripristina una versione precedente del software, tutte le impostazioni verranno ripristinate ai valori predefiniti.

    Follow this guide from the point of recovery to the old firmware **

    When will this be sorted? There seams to be no updates here? Over a week now and it's still happening.Do we have to resort to doing an old firmware install ourselves??

    Same issue here. My Assioma pedals and Garmin heart rate sensor lose connection after approximately 1 minute. It is not possible to make them work again during the ride. have you any updates for this or should we all downgrade?

    Quick follow up and the fix that worked for me: I was very concerned about bricking my device, downgrading firmware is riddled with risk and unless you are an expert  - you should really avoid doing. 

    I stayed on 12.30 and simply performed a full factory reset using the GUI on my edge 820 device - very simple and safe.

    This process took about 3 minutes and then another 15 minutes reconnecting all cadence sensors on my 4 x bikes, setting up Wifi again on the Edge 820, syncing across all my segments and routes and setting up my preferred data screens. 

    A bit of a faff but discovered some great new data that i can now see whilst riding.    

    Tested cadence sensors on all my bikes, then went for a 2 hour ride with no issues, cadence data is running perfectly. I guess the device reset flushes out some legacy old firmware that is causing the cadence and sensor issues we have seen.

    Same issue with dropped sensor connections on 12.3. Strangely, I've done several rides on the new firmware without problems - until today.

    Here's part of the ride:https://connect.garmin.com/modern/activity/4790102725

    Can we look forward to a timely fix from Garmin?

    Could any one from Garmin get back on this? Thanks

    Could anyone from Garmin give some update here? We all have the same problem and feel stupid to factory reset my unit!!!
