Field Maps flickering, showing 'no portal connection' and other odd behaviour

[DataOfficer]

Since the ArcGIS June update last night, we are seeing some odd behaviour in Field Maps (so far checked on android devices running version 25.1.0, build 1529).

We are seeing some flickering or flashing of maps, occasional 'no portal connection' messages and general instability. Is anyone else seeing this behaviour?

No portal connection message

Yes we are also having issues today with Field Maps and also ArcGIS Online in general - gateway timeouts when logging in, attribute tables not loading, layers not loading for some users on Field Maps, and just being very slow in general

Some further odd behaviour a user has experienced whilst trying to load a map.

We are also having issues with AGOL/Field Maps this morning. Random layers will not load in FM or on the new AGOL overview pages. When refreshing the page in AGOL or reloading the map on FM, the layers that previously had errors will load fine and different layers will not load. We cannot use FM this morning due to this. I hope ESRI resolves these issues quickly so we can resume work.

We are also seeing odd behaviour, layers not loading in Field Maps on maps working yesterday. Basemap gallery not available. Offline areas cannot be downloaded.

Offline areas that were downloaded earlier this month have accessible/viewable layers still.
