Wifi Calling dropping out

[Chris374]

Wifi calling has always been problematic - usual fix is to turn off data or go to airplane mode so stupid phones dont try to jump on weak 4g signals. Although tedious to switch off/on everytime I leave the house I have become accustomed to it over the last 12 years!. But what has changed lately? Its dropping out on almost every call. I work from home and its driving me and partner nuts. Weve had full fibre for a month with steady wifi signals. It cannot be the EE handsets as its happening to multiple phones. Yes, Ive reset the router. Any ideas?
