Downloaded the update and its working ok. I get occasional short audio dropouts but I dont remember if I had those in the previous version. Everything else is working as before. Waiting for the paid app update to get approved by Apple so I can buy it...
Update: bought the paid app (cheap!) and deleted this one... So worth it! Big bonus: the paid app will run without being connected to a network!
