Tiles on Apps

Hi,

I set up a dashboard on PowerBI with different tiles (as image) from reports. I put on each tiles the URL link to each report. So in the app version, when you click on each tile (1 click) it direct you to the report. This has been working for over  a year. However, today when I open and check the dashboard. All these tiles are not directing to the report. I can't click them, can't click on the ellipse. Basically, I can't do anything with them now, them become like a background image and no interactivity works on the apps. Please need help asap for this impact our client works. Thanks.
