Update: 16-Mar-22, how can you release an update & not actually fix the issue? Absolute shambles. Google Nest Camera previews (animated gif / thumbnail) no longer working in notifications or in the recent events part of the app, in the app it states 'unable to load, try again'. App data has been cleared, uninstalled, phone rebooted, app reinstalled. Makes no difference. Looking online (Reddit etc) other people are having the same issue.
