WiFi calling has stopped working

[Patternwalker]

WiFi calling has suddenly stopped working on my Samsung Galaxy A51. I've tried the flight mode trick mentioned in other posts but to no avail. WiFi calling is ON, with WiFi preferred.  It all used to work fine until recently but now resolutely shows VoLTE1 next to the WiFi symbol instead of the WiFi phone icon. Any ideas?

Problem solved. The phone had got in a weird state where WiFi was working fine and I could use it OK but the phone somehow thought it wasn't connected! Phone reset sorted it out.
