I get the following error lately when trying to confirm a transaction on the app.We can't process this transaction.Check the transaction to make sure ......?

Hi pgdlaurent , thanks for joining the Community!

Please confirm the full error message as it appears on the app so that we can check this further. 

Usually, if the error is directing you to do it via the web, then it would suggest that it is due to app limitations (such as processing a transaction with CIS).
