Hi Kirk
Thanks for the update. SHP is getting a bit technical for me.
However, I have run some more tests, using other actions as there is nothing I can see that is causing the issue.
I also ran the same tests using Bridge 2019 and do not get the error. It only occurs with Bridge 2020. It does not occur if running an action direct in PS2020
I took two sets of images and on the first ran the sharpen action, on the second set I ran a different action which just changed the dpi resolution from 72dpi to 300dpi and saved the file. I have attached the actions text for you.
As I say this only happens in Bridge 2020, if run in Bridge 2019 there is no error.
I have spent a long time with a Adobe help desk expert, who was really helpful, but concluded that Bridge 2020 and PM are not compatible with sharing some metadata
Thanks
David
