Hi @quichelorraine46​,

I'm sorry it took us a while to get back to you.

For us to help you out, are you able to provide us some information about the app:

• App complete name: 
• Where it can be downloaded:
• Version of Trend Micro program:
• Error message when trying to access the app:

For a while you may try to add the app on the exception list of our program. This is a temporary solution so that you are able to use it while Trend Micro is turned on to your device as the app will no longer be check by Trend Micro when added to the exception list. 

Looking forward to your response.
