Rekordbox mobile no longer transferring latest cue points and tag info

Since using 'Mixed in Key' I have inadvertently overwritten some of my tag information and cue points on my Macbook pro.

I had cues and tags backed up on my iphone (but alas not on an external drive).

Now I can no longer update the collection with the tags (coding text in comments) and memory and hot point cues which are still on my iphone x

Why is my collection no longer updating from my iphone?
