I’m updating the component in the variant look like okay, but when I click prototype still shows old wrong version.
This seems odd. Can you please make a quick video recording from the design panel when you select your frame, then when you click on the prototype view? (Please include the whole window, with the properties and layers panels in view and relevant layers expanded, and select any layers you’re having trouble with so we can check any relevant settings.)
And, it will be also great to share a copy of your file so the community can try to reproduce it. If you can’t share it publicly, please reach out directly to the support team here: https://help.figma.com/hc/en-us/requests/new
