InDesign loses hyperlinks from InCopy (randomly)

1. InDesign Loses Hyperlinks from Placed InCopy Text

Hyperlinks created in InCopy are randomly dropping from InDesign documents. I can find no repeatable pattern or reason.

Documents that had placed InCopy text with Hyperlinks drop the link altogether from the Hyperlinks panel in InDesign.

Problem and Workaround

I found this workaround, and it was fine last month, but the InCopy Hyperlinks are now dropping again!

1. If I create a New document and place the InCopy text with a hyperlink, everything works fine.
2. If I OPEN a previously created InDesign document with InCopy text, the hyperlinks drop intermittently. 
3. My InDesign Hyperlinks panel is sorting alphabetically, so the Securing the ServiceNow AI Platform link should appear in the Hyperlinks panel after the InCopy text is updated.
4. The hyperlink does not appear.
   
   To make it work:
5. Copy the InCopy text frame from the previously created InDesign document.
6. Paste the InCopy text frame into a New document.
7. Confirm the Hyperlink appears in the panel in the new document. 
8. Copy that InCopy text frame from the New Document.
9. Paste the InCopy text frame into the previously created document.
10. The Hyperlink magically appears in the previously created document.

I’ve attached a video of the workaround and screenshots showing how I add the Hyperlink in InCopy, save, and update the modified link in InDesign. 

— I am working on about 21 white papers that get updated every 2–3 months, and this keeps happening. 🤬

2. InCopy Accessibility BROKEN

Also, when I turn off Shared Hyperlink Destination (which was another whole can of worms a few months ago) and add the Accessibility text, that accessibility text gets completely REMOVED and doesn’t carry through to the PDF!

Steps

1. Add a Hyperlink in InCopy.
2. Un-check Shared Hyperlink Destination.
3. Add Accessibility text (for the visually impaired).
4. Click OK and Save.
5. Place that text in InDesign.
6. Open the InCopy text (in InCopy).
7. Double-click the Hyperlink.
8. BOTH settings are GONE.
9. Shared Hyperlink Destination is BACK ON, and the Accessibility field is EMPTY!

This InDesign issue with placed text from InCopy keeps coming up. It popped up a little over a month ago. I found a workaround, and now the hyperlinks are dropping again. PLEASE HELP!

This issue keeps rearing its ugly head. Please fix this, ADOBE! It popped up a little over a month ago and keeps coming back randomly.

2. InCopy link modified in InDesign:

   

3. Confirmed link is there in InCopy and saved:

   

    

4. InCopy link updated in InDesign (after confirming the link is correct in InCopy):

   

5. Still no Securing the ServiceNow AI Platform (with no number) hyperlink:

   

    

6. Created a new doc, copied the InCopy text from a previously created InDesign doc, and pasted that text frame from the new doc (confirming the Hyperlink is there):

   

    

7. Pasted the InCopy text frame from the new InDesign to the previously created InDesign white paper: 

   

8. Hyperlink is there!
