Just changed to the Tomtom GO app, having used the old Western Europe app for 3 or 4 years.
I suddenly had a problem with the voice instruction only working intermittently, so, having checked everything in the app settings and iphone settings, to no avail, I downloaded the GO app.
Here, again the problem is exactly the same.
I can see on the screen, that the voice instructions are on, my volume on the iphone is up to maximum, percent voice to music (which I don't play) is at maximum.
In settings clicking on the voice 'Jane', makes her talk.
Everything was working, on a journey this morning, for the first time, then later, when I came to use the app, there were no voice instructions, despite no changes made since this morning's success.
So, what am I doing wrong, having used this app successfully fo so many years, what has changed ?
