Hi, welcome to osm.
I fixed the phone format on both your edits.

Hi, I reverted this change because you accidentally dragged a road node across a few streets.
Can you edit it again to make the changes you want.

no response, edited tags

no response, deleted

no response, changed to clinic, fixed opening hours

Finally rendered the four islands I added a coastline to but only on zoom 15 so far

Hi, I have reverted your edits as you have added the business to a suburban roadway that is obviously not at the address you have listed for the business.
You should add a node within the city building you listed and add the tags to that.
You may find it helpful to use a site like https://www.onosm.org/# to add the proper tags.

I added a coastline to Fairway Island to get it to render on the standard layer (and the Tracestrack Topo layer).
Another three island within the coastline were also affected and already had a natural tag. I the changed them to single member multipolygons and added natural=coastline to the way so that the ways did not need to be duplicated for the natural=coastline tag.
Feel free to revert/remove/alter if that doesn't suit.
Coastlines take longer to render...

Thanks Rowan, I’ll do that tomorrow if time permits

Is the building named "The Mill Markets" on OSM the same site.
If so, should I merge you info to the building and use the name you have provided instead?

Hi, you have placed this business on the footway. Can you place it over the part of the building it operates from thanks.

Is this a hospital or a clinic?
amenity=hospital
amenity=clinic

Not sure how soon the changes to rendering of multipolygons may take.

I added another water relation MP but it hasn't rendered the island as yet...
relation/18088652
Maybe having these two separate water mp around the island causes the problem...do there need to two separate areas?

Yes, I found it quite complex and couldn’t make much sense of why it was mapped as it is. Good luck sorting it out.

Because of the discrepancy between the business web site listed addresses and where you have mapped the business, I am inclined to delete this entry.
Can you explain why this mapped address should remain thanks.
Is it because not all of the businesses office locations are listed on their website?

I think you will find that because the coastline has followed all through these canals instead of being closed of near the coast, you will need to add a coastline to this island too. I think the outer role was correct but didn’t check closely.

…err, english version
barrier=gate

Hi ShaunKolo, incorrect gate tags were added here
See our wiki for the gate tags…

Thanks, looks good.
