Yes, i have had to restart the device and it has helped Yeah, if the page uses up significant memory or has lots of detail (typically animations do this) It will reload. I use mobile and this happens to me almost every day and I’m not so sure if there is a solution to this. It probably is just because your device can’t take the loading of the project or the amount of scripts being run? But it also might be a browser issue. I often just manually reset my iPad and scratch runs fine.
