I love the app. So far I had no problems with it at all. The only thing that bothers me is the speed of your portal. Every action takes at least 3 seconds or longer. In some cases from 8 to 10 seconds to forever. Comparing tracks is close to impossible due to the missing speed. I tried the page from several different locations: home (fibre with 36 MBit down and 2 MBit Up), office (about thee same), and a friends’ place (20 MBit down and 1MBit up). Everywhere the same problems.
BTW: I am located in Austria (Europe).
I just wanted you to be aware of this.
