Fiverr App glitching a lot

[aashishah]

Firstly, The app isn’t giving the correct amount of earnings and often subtracts or adds amounts on its own. The figure is rarely correct.
Secondly, It’s showing me that I do not respond to messages on time and that ‘I reply very slowly and that I should be more available.’ This happened only once, when I was 6 hours late in responding because time zones. Every other time I’ve responded in the matter of minutes.
This is ruining my experience.
