The 2021 update is really good. I like that things are explained up front. I.E. the expression Hilf mir.
Before I didn't understand why mir was used instead of mich.The explanation was given allowing me to retain the expression easily. The difference between You speak good German and You speak German well also has made things clearer. Also I seem to understand Lena better than the previous lady speaker.
Also greatly improved is having the German letters with the Umlaut and the double SS available in the written portion while using the
computer keyboard. also makes the written portion easier by being able to concentrate on proper spelling instead of hunting for the special characters on the little keyboard.

Thanks for the improvements.
