Using apps on a mobile device

Apps are not working on a mobile device. One of the apps we are using in monday is Quickley.
The main reason for using this app is that we can easily communicate with our clients via whatsapp.
They can send us a whatsapp text and quickley pushes the message to our monday board. Then we can respond via the monday board and our client receives a text message. But we can only respond on our desktop bacause apps are not working on the mobile device.

So on one hand you use an app bacause it can improve the communication on the mondayboard but on the other hand with a mobile device you cant communicate because the app isn’t working
