Thanks for all your feedback regarding this!
The fix for this is already in the pipelines. I don't have an ETA for release but I'll keep you posted.
Meanwhile, you can go to Navigate To > Address and supply the first part of the post code and then select the result. You will then be asked to choose the street expected. This is obviously less than ideal but hopefully helps you find your destinations until we get the fix out.
We're very sorry for the inconvenience this is causing you!
Thanks for flagging this!
I've reported this to the product team and they're looking into it. I'll keep you posted.
