The only workaround that I found is to have zinertek aircraft realistic lights installed and that fixes the functionality of the interior and exterior lights. Unfortunately this is the only way I’ve found it work since it’s a paid add on you already have or need to get. Least there’s a way until an official fix is published

Hope this helps anyone not wanting to park the a350 back into the hanger until it’s fixed. I did it myself and it works flawless

As a work around for this issue someone on the discord recommended to have zinerteck aircraft realistic lights installed it fixes both the exterior and the interior lighting. A great work around to restore the lighting until an official patch is made on the Xbox platform
