I try to implement already build app in PHP to Teams custom tab. Page works fine but I need some data from teams. All data I need are provided in placeholders as noted here:
https://docs.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/access-teams-context
The problem is that if I insert any placeholder like ?tid={tid} I get a blank page. I can't find a way to debug this to find what's wrong.
Basically I have a simple PHP applications where I need to read $_GET data but for some reason when I add any placeholder I get a blank tab. Anyone had similar issues ?
