We are aware of some layout issues on older browsers, but most reports of this appeared towards the end of last year. I'm not sure why there appears to be a new spike of problems, but am passing reports along to the technical team.

While we would love to support older browsers, the number of people using them is pretty low thanks to auto-updates, so it can be hard to justify developing for them - but I won't rule out us being able to make some tweaks.

In any case, if only for your own online security, we very strongly recommend updating your browser (or OS) to the latest available for your device.
