Ads not displaying in my app

Hello I am Panos , from GO4GAME App Company. I hope you are doing well during these times. I would like to let you know about a problem I am having with one of my apps. I have published an app since last year called Battery Care - Health :https://play.google.com/store/apps/details?id=com.panoskaragiannhs.BatteryMngr

It has been doing really well but I cannot display ads.I think that Thunkable has disabled my ability to display ads on this application due to false alarms caused be Google.

Could you help me with this? I would really appreciate your response and action on this!

Have a nice day !

Panos
