Hello!

I used code from [https://appiumpro.com/editions/5](https://appiumpro.com/editions/5), downloaded all needed dependencies and I am still getting error: failure|564x89

I do not know if methods are already obsolete or I forgot to put some values somewhere …  
If there is need I can upload my code.

I would be really grateful for any advice.
