Hi @Mark King
Thank you for posting your question in the Microsoft Q&A forum.
Based on the information you have provided, looks like you are missing the log in panel and search bar.
May I know if you choose Anyone option when sharing?
If yes, this doesn't require a Microsoft account. So, users won't have access to all OneDrive features such as Log in and Search bar.
I have tested and my outcome similar with yours.
If you want them to have search bar and log in panel. Please choose other options that require a Microsoft account. These features will appear again.
I hope this information helps.
