Libere 3 sensor shows "Signal Loss" with iWatch8 also on my arm.

I am using libere3 sensor and also have iWatch8, it seems like the iWatch8 is drowning the Libere3 Bluetooth signal. When I removed the iWatch8 and kept it out of range Libere3 seems to be working fine. At present I am not charging the iwatch8 so it does not interfere with Libere3. Support staff are non technical and they do not understand the issues and Abbot does not provide a way to report technical issues.
