Issues with voice guidance tomtom Via 52

When my Via 52 gives out voice guidance I’ve noticed a couple of things that didn’t used to happen. When giving the distance to a turn etc the voice pauses, i.e. in 200 ‘pause’ yards. Not a massive issue but doesn’t seem right. The second is on an approach to a roundabout it used to say for instance, ‘turn right on the roundabout, 3rd exit’. Now, on the first instruction it omits the exit number so just ‘turn right on the roundabout’. Not until I am actually at the roundabout is the exit number given which is annoying when trying to be in the right lane at a large roundabout. Has anyone else had this issue / been able to sort?

TIA
