Missing colon on numeric keyboard – Google Sheets Review

My only use case for this app is to edit a spreadsheet full of times formatted hour:minute, e.g. 9:32. Every time I select a cell, the app switches my keyboard to numeric. This is the phone’s numeric keypad designed for dialing and it doesn’t have any symbols. To supplement this, the app provides a row of symbol keys that is deficient in that it doesn’t include a colon. How am I supposed to type times without a colon? The only way to get a colon is to switch the keyboard to alphabetic and then switch to symbols … over and over again in every single cell I want to edit. The android app has a colon in the supplemental row of symbol keys, but in its place the iPhone app has…. A semicolon??? A severe value loss. Please fix this!!!!!!!!
