Synapse 2.0 is not providing function to edit macros

Dear all, hope you can help with my Razer BlackWidow Ultimate Stealth 2016: when starting Synapse 2.0 I don't see the option to create macros, there are only options to register a product (done), to visit the store and a link to a page with compatible devices. In the past I have had some macros running with the Razer keyboard, all was working fine. In the meanwhile I have switched to another keyboard since I was not gaming any more. Now since I'm gaming again I want to use the gaming keyboard, but can't edit or select any macros. I tried some former Synapse versions without any effect, have updated the firmware and the keyboard driver is also known to Windows 10. I appreciate any hint to solve my issue. Thanks in advance!
