Per the FAQ here, Legacy Analytics (a.k.a. Unity Analytics), will be shut down Dec 31, 2022. We have a number of apps in production with Legacy Unity Analytics implementations (with various versions of Unity). What should we expect to happen after Dec 31 for apps that have not been upgraded? Will post attempts from the app raise exceptions, crash the app? I'm really worried that we'll realize devastating effects of Unity turning off the service too late for apps we cannot afford to upgrade by end of year. Can we request extensions of Legacy Analytics service for specific apps we cannot upgrade?
