This happens too in Linux Mint MATE 19.3 (in my case 64bit) Stopping and starting the applet does not help but logging off and back on again soves this iommediately. It occurs since the change from the old separated applets to the "unified XApp Status Applet" combines the status of updates and network. Simulating it is hardly possible, it's more a gamble.
