I am unable to open the App on my phone. I have uninstalled it and reinstalled it and still not working, It's been out of action all week.

I understand how inconvenient it is to have the app out of action all week, especially when you rely on it for your business. Since reinstalling didn't work, I recommend connecting with our Live Support Team. They can look into the root cause and provide the necessary fix.
 

In the meantime, I recommend accessing your account through a web browser so you can continue with your daily work.
 

Please don't hesitate to reach out if you have other questions.
