When talking about the standard of customer service, it is perfect, except for a few times when the response was a bit slower than usual, but i guess it was just a matter of bad timing. Now, let's set the money talk aside, i will just say this - if you follow all the rules, you won't have any complaints about the financial operations. Speaking of the interface, there are a few quirks with the Windows app. Additionally, the Android app can feel unresponsive on my Galaxy phone. One drawback of the Windows app is its inability to display multiple graphs simultaneously. Happy to contribute to this panel
