Hello everyone,
I am currently testing my application on my mobile phone and on the browser.
When I am testing the App in Power-Apps "editing-mode" the buttons work like they should:

the "kommen" button is enabled to start the timer.
the "X" button is disabled until you press the "kommen" button. After that the "kommen" button is disabled.
the "gehen" button is also disabled until you press the "kommen" button. After that the "kommen" button is disabled.
But if I use the App via the link for the browser or on my mobile phone it looks like this:

all buttons are enabled but from the start there should only be the "kommen" button enabled.
I am working with this code for the "kommen" button:
If(varNewItem.'Active Session'=true;DisplayMode.Disabled;DisplayMode.Edit)
"X" and "gehen" button share the same code:
If(varNewItem.'Active Session'=false;DisplayMode.Disabled;DisplayMode.Edit)
once i click on the "kommen" button I activate an active session on my sharepoint list.
any suggestions?
