Thanks for the update. I’m also experiencing this issue with an ARCore app that works in 5.4.3.
I can continue development in 5.4 for now but will also examine the source code to see if I can make a local workaround. If anyone else has already done that, please share the info (as I will do, if I’m able to solve it). The issue tracker says the projected fix is 5.5.3, so probably “not soon.”
Victor: Which branch on GitHub should I watch to see when Epic’s team are working on this? I looked at the list of branches and noted more than one which seemed potentially relevant.
