Hello Sandalss;
Thank you for your contribution to OpenStreetMap Oman.
I noticed you added an access tag at the highway=crossing,
For examples:
Node 8345751489
Node 8345848685
Node 8345848583
Node 8345891657
Node 8345891661
Node 8345891660
Node 12692882938
Node 8638670062
Node 8638670061
According to the OSM wiki documentation for highway=crossing, the use of an access tag with this feature is not mentioned or documented as standard practice.

If you have different information please share that with us, if not please fix that.
Best regards.
