Seems to have fixed the issue after a recent update on my Huawei P Smart phone

A couple of days ago, I received an update for my Huawei P Smart  mobile phone and today, I tried accessing the only WiFi I knew I could not access since having this phone. It seems to have worked, as I am now writing this post while using the WiFi.
Customer service at Huawei did tell me in their last email, to give them time and they would work on it. I have logged out and back in on the WiFi to check it wasn’t a one-off just being able to log in, like when I downloaded Firefox browser and I was able to log back in on the WiFi. So if you are having same issues and have not updated the system on your phone, I totally recommend you do it and you should hopefully find like me, that the WiFi issue has been fixed.
