I have am using a educational license and have been teaching Maya for 17 years. I can find not other way to file a bug report with my level of access, which is lame IMHO.
Maya 2022.1 & 2022.2 updates introduced a major bug: Tiff file textures w/ alpha channels do not render correctly, apparently blue channel is missing from alpha, green channel from color. This is not the case with the original 2022 version.
