The new, faster format is great, but there are some problems. First, when you have practised an area that needs strengthening even clicking 'continue' doesn't get you back to the tree, and you can't get back by clicking on the language in the menu either. The only way I've found is to go to another language and then come back, which isn't practical. Second, with some lessons, when asked to 'type what you hear' you don't hear anything, which leaves you with the only choice being to 'skip', but if you do that it will eventually ask you the same thing, but still without speaking, and unless you remember what the answer was when you skipped then you can't finish the practice. Please help by sorting out these problems.
