I tested with a brand new farm with May Update, Word document in library can be correctly checked out/in under modern UI with Chrome. You can have a test with this update. ( I witnessed the issue like this post, so you may need to install the language pack too if you have similar problem. )

The question about Power Automate custom connector will be out of the scope of Microsoft Q&A forum. And as I am not an expert about Power Automate, I will suggest you to post your question in the Power Automate tech community. The engineers there will be able to provide more help about it.

Are you using Claim-based authentication in the SP2016 environment? You can have a check on the IIS log and event viewer for more detailed information about the error.

Hi, @sns1 ,

I mean the screenshot of the page when editing the link. If the link cannot be deleted, it may be a link added by SharePoint.

A common scenario will be that, structural navigation is enabled and user check on display subsites, then the link to subsites cannot be edited. Here is a thread quite like your description. Ask your customer to have a try uncheck the subsite and test again.
