Update is a joke

[sweet5]

My phone updated, my wifi calling has disappeared off my Samsung S10 I've tried everything, can't make conference calls either, changed  sim, cleaned port, turned phone on and off 100 times!

@sweet5: I'm sorry to hear that you have encountered this issue. Please can you try removing your SIM card, restart your S10, then put the SIM back in to see if this helps? Head to the Phone app > Tap the 3 dots in the top right > Settings > Wi-Fi Calling, or swipe from the top of the screen to the bottom using two fingers to check for the Quick Panel icon.

Hi,
I have tried all them steps, but still the same issue, it was fine before the update I've took my sim out number of times still nothing. And my signal for Vodafone is appalling on top of it.
