Taking huge amount of storage. More than 1gb. App by itself less than 100 mb where does other date go idk. I did try to delete all call history and I didn't have any photos or videos on duo. Was using only for calls. So why taking 1gb additional data idk. To remove it I was forced to delate all data and lose profile. Quite bad experience. Btw for calling is good but taking too much data for nothing
