@sid9-3 this might not be intentional, so we should figure out if it is or not. First, do you have anything listed in edge://crashes? If a tab crashes, it will have to reload. Next, are you closing Edge at all when you see this happen? When Edge re-opens with previous pages, it sometimes doesn't load all of the pages until you click on them, which may also appear as if they're reloading. One other possibility is that your machine is very low on memory, in which case Chromium-based browsers automatically unload tabs in order to free up space.
The only way for this to be intentional that I can think of is if you're the lucky recipient of a feature we're testing to unload not-recently used pages in order to reduce memory and battery usage. However, I don't believe we've actually started rolling this out yet, so the only way that would happen is if you've manually enabled it by turning on the flag. You'd know if you were using this feature if you see tab titles fading a while after you've left them untouched.
