Imovie won't download on my MacBook air
I have been trying to download iMovie onto my laptop, and in the app store it says "accept" under iMovie, when I click accept it then asks for my apple ID info, I enter it and nothing happens. A few minutes later, it just says accept again and goes through the same process. My computer does not need to be updated. When I check for updates, it says there is none.
MacBook Air 13″, macOS 10.13
