I can however delete the same data in the web app. Data is stored in a hosted feature layer. I get a JSON error when trying to delete any feature in Field Apps version 23.1.0.
What are some things I can check? If I remember correctly, a JSON error is sometimes related to the object ID? I've already checked the configurations in the Web Map to make sure that features can be deleted.
I am having the exact same issues. I can delete in the webmap and in Collector but get this error in Field Maps on iOS and android. Did you find any solution?
I am still able to delete features in Field Maps 23.1.0 on iOS.
Are you logging into Field Maps with the same credentials that you are using in the web map?
