Side nav doesn't align correctly on some devices
Something needs to be fixed in the css to make sure that the sidebar navigation works across a range of Apple devices alongside Safari and some Google Nexus models. Although providing support to these devices is not top priority, there is obviously a problem with flex css that should be resolved for consistent layouts.
Please note: flex issues can only be fixed in iOS 9+ and Android 4.3+. In lower screen sized Apple devices (<= v8), the mobile menu appears stacked - a bug that can't be fixed in Safari even with -webkit prefixes.
