Hi, all
I got 2 questions about the "Share record" function on model-driven apps, the new modern UI of which was recently released.
1) Sharing a record with certain users and re-opening the share-pane again to modify the share setting, it says "Unable to retrieve links shared with users." So, I can't change or remove the set permission. Does anyone know the cause or the measure to take?
I used a user with System Administrator role, and checked the same issue happens on any of Chrome, Microsoft Edge and Firefox.

2) I would like the "Share record" setting to be inherited from a parent record to child records. So, I made the setting for the relationships, choosing "Parental" and "Cascade All." But no sharing is inherited. If someone knows the cause, it'd be a great help for me.

Both of the two issues had not occurred when I used classic previous UI.
I assume I possibly could make them work without any problems if I used classic UI. Is it possible to switch back the modern UI to classic manually like we can do on views and forms?
