Hi All, I wonder if I am the only having issues with HR bands since version 12.  Long story short:
1) i did the upgrade to v12 couple of months ago, as soon as i did, i started to had issues with my HR band (old one shipped with FR 610 but working fine till that moment - i have also changed the battery). My band started to send erratic values and having issues when connecting

2) I had several chats with Garmin tech support, and we've not found any way to fix the issue. even I have send it to them, but it is still same status. They send it back to me with no comments Thinking

3) I did the upgrade to v13 and it is in the same status. currently What i have detected is

- My F5S+ is  able to find my band

- seems to connect with my band

- it send some values (few seconds) to the watch but suddenly it stops sending values and I only see -- (2 dashes)

- if i change the window, it starts sending values again, but after few seconds it stops 

I would either to get a version solving my issue or downgrade my sw version to version prior 12 and potentially downgrade my ANT/BLE/BT to version below 6.06. 

I don't see where to get these old versions, is there any repository?

Honestly, i was very happy with my watch but now I am starting to be frustrated and even thinking if makes sense the investment done in garmin watches.

An help is welcome (in parallel I will call again to the support service)

Thank you
