Account valuation issues

Is anyone else having issues with the valuation of assets in their account? My Berkshire Hathaway B shares have dropped in value by 600 in the last couple of hours despite the share price being up today. The valuation has bounced back briefly and then dropped again (I have screen shots from the app). Anyone know what is going on?
