Version 3 have problems – Acrobits Groundwire Review

This have been for me, one of the best Softphones programs of all, but since this new version, it freezes a lot, you click buttons and it responds 10 sec later. I like a lot more the last version. I have an iPhone 5C, please fix this because I can't really use the app, unless I wait several seconds before I can use it normally.
