Change financial year

I've had that happen too. I asked support about it and apparently it's a bug on small screens (it works fine on standard laptops or PCs) that they're going to fix as soon as possible. I got this answer:

Hello Adrie,

There does indeed seem to be a bug on small screens (smartphones, tablets and small laptops). Zooming out should solve the problem. Our IT team is doing everything to do to solve this as soon as possible. If you have a PC or standard laptop available, you can work on that, as it does work there.

In any case, we apologise for the inconvenience and hope that this will be solved soon."
