Is anyone else having any issues accessing the UI from Safari? I get through the login page but then just get a blank screen. It works fine on Firefox.

Not sure when this started happening, it could have been with the newest firmware release (3.9.6.1) but I mainly use Firefox, so can't be sure. If anyone has seen it and fixed it, I would be delighted to hear how!

Resetting Safari (which clears caches, cookies etc) usually resolves issues like this.

Sadly it doesn't for me. No real issue I can use Firefox.

I have seen what you’re referring to but only on certain pages in the WebGUI.

FWIW, I use Safari on macOS for all browsing except the Vigor GUI (Firefox for that as it works better). Ironically it works fine with Safari on iPadOS.
