After previewing a form once, I cannot seem to preview again after having made some changes. Is there a limited number of times one can use Preview? The Preview button no longer displays after first use.

This is not the expected behaviour. The preview should be able to show the changes and there is not limit. Can you help share the project URL you are facing issue to customervoice@microsoft.com for us to investigate ?
Thanks,
