I only saw the thread title - I assume they meant in general - thread didn't make it clear it was a new issue. My hotkeys have remained however I am currently on the beta branch. it works on the beta branch; not going to uninstall it to test on the live branch. So if it doesn't work - apologies; it did before and it does on the beta and it has saved my changes.
