I work in IT. Because of COVID, I'm now a 100% work from home as well as the rest of my team. Now that we're all distant, when we're having a system issue where we need all hands on deck, I have a hard time getting ahold of people. Its not like at the office where an emergency happens and I walk to the cubical and get there attention. Can't do that anymore. So, im looking for an app that, if all of us have it installed, if a message is sent to the group, it would be obnoxious noises to get everyone's attention. It would be nice if we could change the priority of a message so we could send a low priority message too. It would need to work for Apple and Android. It would be nice if it was like an amber alert where you cant ignore the message.
