Realitiy Composer file size and iOS 18

Hi folks: I've been creating .reality files out of Reality Composer for over a year. Some of the files are up to 500 mB and, prior to the last month they opened fine as AR projected experiences on even basic iPhones and iPads. Now, I think since iOS 18, a 64Mb file will open as an AR experience but files it seems from about 350MB up don't open. Files just opens a window displaying the name of the file, that it's a .reality file and the file size. But it no longer opens into either an AR or Object display of the .reality scene. Has there been a new file size limit put on .reality files that Files will open or what else is going on here. Have a client who was about to launch and experience based on the .Reality file I can no longer open. Please help.
