I am developing an app using the VPS from immersal ✗ 8thwall.

I am using immersal’s map data and trying to localize using the official immersal source code. However, sometimes the camera position suddenly jumps. If you have any insights into potential causes or solutions, I would greatly appreciate your assistance.  
(I took a video but got a message saying new users can’t upload.)

Environment:  
・iPhone SE Gen.3  
・iOS: 18.3.1 Safari  
・8th Wall XR Version: 27.2.6.427

Are you able to upload the video as a new comment and/or upload the video on an external service like Youtube/wetransfer and share a link?
