The idea is great ... an app that not more than one page of authorizations requested (such as the GMX-app). It is not obtrusive displays advertising (as is the case for the mobile part of GMX, where you will literally prevented by logging off). All I really like! Really Great!
Only the most important function: log me in my GMX account, unfortunately, does not work (although GMX is listed in the list). Please fix the error ... would indeed be really awesome.
