This is basic device management that I am mentioning, every person using a device, be it pc, laptop, tablet, phone should be making this a regular routine for device maintenance ie at least monthly or bi-weekly if using app/s that are frequently updating their programming (like ourselves). I especially mention this here as I do not think everyone realises how their devices use caching systems and how they store outdated data to load sites faster. This outdated data is what causes most display issues. Why the support team are constantly reminding players to be mindful of this especially after any version update we make as we do fundamentally change a lot of programming with these; so when your device still keeps the old codes we deleted and then cannot load the new ones (as they block them) this is when all sorts of odd display issues can and will occur.
Does that help?
