I set minecraft preview to update in the bedrock edition section of minecraft launcher and i go to another window for a while and play online games, i come back, its not done, I've reconnected my internet, restarted my device, and have tried to get minecraft preview to update but it just has not worked at all, my internet connection is fine also. My ping for example on lifeboat or cubecraft is below 50 most of the time, so i know its not my wifi, but it could be either my device or operating system because the launcher has just showed me the text "waiting on install" for a couple hours without actually installing anything. I've had this problem in the past and i dont know what resolved it last time but this shouldn't be normal.
