App not working says route not found must not be a route – Transit Navigation Review

I had this app for a good while and now it’s not up loading anything any address location to and from it will tell me route not found long distant or local areas is there a way to get this fixed? I have deleted it and reinstall it and it’s the same thing and have tried from different locations I have been at trying to see if it connects. Thank you in advance
