Wi-Fi & data issues OP 13 (EU)

Has anyone else been having issues with connectivity since the latest update? I don't know for sure if that's what's caused the issue but it's the only recent change I can think of, and it's only my phone that won't load pages (i.e. laptop, tv etc still work on same Wi-Fi).

Whenever my phone sits idle for a few minutes/hours or when I leave it overnight while I'm sleeping, whenever I go to use the device again I can't load anything. No apps, no web pages, nothing. Mobile data & Wi-Fi don't work, despite showing strong signals & in my usual places (home, work, etc.). I have to restart the phone and then it works until it stops working again. Anyone had a similar issue? Any fix or am I just stuck waiting for the next update?

Thanks
