Hangouts is, no doubt, a very unique piece of software. Here I am, just reset my phone, and Hangouts decided that it’s about time to show me notifications from 1 year ago (about the time I last used it). Those are not unread notifications or anything, it’s just happened a year back then and it decided that I probably need to know. What a motto: “a chat/call software that have no idea when and how to notify you about stuff that you use it for”
