I have a web map with a feature layer and four tables that I created forms from using the Field Maps Web App. I created the forms about a month ago and had no problem creating forms for the feature layer or the tables. After the update last week, I am no longer able to configure the forms for the tables. The tables are greyed out in the content tab of the fields maps web app editor. I try to click on the table, but I cannot and when hovering over the table I get a message saying, "Editing of the content is disabled". I am still able to use the map on the Field Maps app. I can see the forms for the feature layer and tables and am able to submit a record in the tables using the app. So it appears like the forms are still there, I just can’t see them or edit them in the web editor.
The layer and table in the map come from a feature service published to ArcGIS Server 10.9.1. The service has been added to ArcGIS Online as an item, with the credentials to view the service saved in the item. There are relationships between the feature class and tables, with three tiers of relationships (the feature class is related to 2 of the tables which are each related to another table). Everything is versioned (traditional), has global IDs and editor tracking. The relationships are built off the global IDs.
