    Helllo,

    I am seeing the following outputs when debugging a memory crash.

    "WARNING: RGBA Compressed ASTC6X6 UNorm format is not supported, decompressing texture"

    I found that this is the default format for Unity and iOS devices.

    I also found that it wont work on older iOS devices, but my understanding is that the ipad mini 3 should be fine.

    Any ideas what might be happening here?

    Thank you
    Les

    No, that's correct. The Mini 3 uses the A7 SoC with a first generation Rogue PowerVR GPU. The A8 (used in the Mini 4 and iPhone 6) was the first Apple SoC to support ASTC.

    (The iPad Mini 3 is the same internal hardware as the Mini 2.)
