Hey Daniel, the most common reason for prototype performance issues is the file’s memory limitations. At the moment, the workaround for prototypes not loading or loading with problems is to reduce the overall memory of the Figma file. This should help with any prototypes, regardless of the device or operating systems. Tips on reducing memory can be found here: Reduce memory usage in files.
Please try out the steps indicated in the Help Article and if you still run into any issues feel free to contact our support team with a copy of the file so they can see if they can replicate this issue.
Hope this helps!
