Hi spm_no
When I was struggling with this I noticed that the two LE connections on my phone had the same names: mine were both named LE_L-KS , this seemed odd to me and when I was on a help call with Phonak they asked me to go back to Costco and have them change the names to LE_R-KS and LE_L-KS. The Costco technician called Phonak and walked him through changing the names but the problem was still there and Costco told me Phonak would push out an update to the app or that something on my phone was conflicting with the app.
The odd thing was that sometimes I was able to create, save and update programs but at other times the error messages would appear. I finally figured out that if the regular bluetooth was disconnected the app worked fine.
I think it would be helpful if you called Phonak and see what they tell you about the naming of the LE connections.
I am including some screen shots for your information. Please let me know what happens.
