Synchrinisation problems (Android v.2.0.8)

Hey,

am I the only one to have those problem synchronizing contents to my phone or am I the only one trying to use chinesepod on my phone? No matter lesson content or vocabulary synchronization doesnt work properly for me.

Some weeks ago my vocab list was obviously synced with another account from one day to the other (online I had just around 100 vocabs but got synced more than a thousand). For sure I didn't change my credentials.

After reinstalling those app on my phone things worked fine for a while but now vocabs wont get deleted on my phone once I delete them online. In order to focus only on those words I dont know yet I delete those I already learned but they wont disappear from my phone. Means my online vocab tool stores around 300, my freshly sycned phone around 400.
