That below is from the Stromer Site. I could not paste a link, or I would have. They had another update last month as well and I am confident they are on top of it, although frustrating when you can't use your bike when desired. General Stability Improvements is noted in the update, without specifics given, but this may remedy problem.
I am still wondering if the problem could be driven by the IOS platform used with Omni as they interact. I do not know if the code has the ability to cause issue or if it is a hardware BIOS issue.
It may be able to be isolated to a specific App type or maybe not.
