First post and new to the app.
I want to write Keywords to my pictures but I seem to be unable to write IPTC:Keywords although XMP:Keywords are fine. I get the following for all IPTC entries
Cannot Be Edited
Source: iPhone 8/XR
Why are all IPTC entries read only? It seems to be limited to heic pictures.
On a second note, is it a good idea to try and write the keywords to both metadata standards? Is one sufficient and if so which one. I want to write to both to increase visibility in different apps.
Thanks for your help.
