Quest 2 V56 compute shader group shared memory issues

There seems to be a regression between v55 and v56 regarding the use of group shared memory within compute shaders on Quest 2.

Certain compute shaders using group shared memory which used to work in v55 are now failing to link, without any information as to why.

08-22 12:21:33.112 15136 15185 E Unity   : -------- GLSL link failed, no info log provided.

I can get these to link if I significantly reduce the amount of group shared memory used, but in these cases I have to reduce it to the point where it is practically unusable for the collaborative buffer loads I am doing.

This leads me to believe that there may have been a change in the maximum amount of group shared memory that is able to be allocated by a compute shader work group. However, as these compute shaders used to work just fine, this appears to be a regression.
