I use a couple taskbar pinned websites. Namely Facebook and Amazon. These are pinned from IE11 since Edge doesn't support. Useful and if I right click all sorts of handy shortcut. However, initially the pinned icon (or favicon) was the nice 64x64 type but over time the icons have reverted to unsightly 16x16 and I cannot get them back to their former glory. I have tried unpinning and repining them with no joy. Sometimes the facebook one reverts to the 64x64 but within days/weeks it returns to the unsightly small icon. Is there anything I can do?
