It is not fixed in the new firmware but I am pushing - there are a few technical programming niggles to sort out. In the mean time if this is a big issue for you it may be an alternative for you to use BT stream on your phone.
I'm happy to help if you have any issues with your unit but if you just want to keep up to date with latest firmware and news + support, I provide this for a one off subscription fee of $25 AUD.
The procedure should be identical to when you first set up the unit - can you describe in a bit more detail? If you choose select GPS file path, you should see a folder "Primo2", choose that folder, then swipe up (this is laggy I know) to scroll down the list until you see Primo.exe.
