Forms Designer Forum

Hello Katy,

I'm sorry for the delayed reply.

Thank you for sharing the form, the settings and the code are correct.

Does the same problem occur on all forms and lists?

When you've tried to reproduce the issue on another form, have you used the same child list?

Do you have any filtration in a Form list view for POItems lis?

Sorry, I was on vacation )
Yes, the issue occurs everywhere - i tried on a separate site collection with completely different (newly created) lists - still the same.... Have you heard that any of MS updates might cause this? or interfere with the forms?

Hello Katy,

Have you used Related Items on a new forms previously? If yes, are they working now?

Do you know if any updates were installed on your tenant?

Could you please record the video showing how related items are working on a new form, including the console logs.
Also please share the screenshots of the form settings, the code you are using and the screenshot of the source list. We need this information to reproduce the issue on our side or detect the errors.

Yes, we used Related items before and they were working fine. Now they are not working anywhere.
Here is the list of most recent updates:
May 2021 Cumulative Update for SharePoint
Workflow Manager Cumulative Update 5
Service Bus 1.0 Cumulative Update Feb 2013 which is the most recent (KB2799752)
I will make the video and attach it later here.
