Hi @James_Fawdry, Thank you for reaching out about this.
I tried to replicate this issue but haven’t been able to do so yet. I applied Drop shadow and Inner shadow to an ellipse, but the appearance remains the same when switching to the Prototype tab or viewing the flow in Presentation view or Preview.
Are you experiencing this issue in the browser, desktop app, or both? Could you please try clearing the desktop app cache and browser cache to see if there are any differences?
If the problem continues, it could be challenging to determine the root cause without reviewing the file itself.
While we are waiting for input from our community, I can create a support ticket on your behalf. In that ticket, you can provide the file link for our support team to examine more closely. Please let me know if you would like our support team to assist.
