Translations:Portals/10/en

If a portal is leading to a world that is not compatible with a certain platform, then users seeing the portal from an incompatible platform will not be able to enter the instance. Instead, the portal will have a red "X" icon surrounding it. It is generally considered mindful to be aware of friends and acquaintances who may be on other platforms before going to another instance so that they don't get left behind due to this.
