InDesign link alt text not transferring to PDFs

[KTdid.]

For the past few weeks, in all interactive PDFs I've exported from InDesign 2021, the link alt text I have set in ID is being stripped in the export process and not being transferred to the link annotations in the order panel OR the Link - OBJRs in the tags tree. 

This is a massive headache and time suck. 

Has else experienced this? Have you discovered why and have a solution? 

Thanks! (I will cross-post in the InDesign forum.)
