.MTS file audio sync bug

I'm curious if there is any update on the current bug that affects .MTS files having out of sync audio. I've called customer support multiple times to no avail. I've reformatted my projects to use an older version of premiere that doesn't have the bug, but I'm no longer able to use my previous after effects compositions with the dynamic link. I have multiple long-term projets that I've been editing for over a year, with thousands of .MTS files, and hundreds of dynamic link compositions, so I'm not able to use some kind of exterior workaround like handbrake. I'm basically at a standstill on some major projects because of this bug, and considering trying another editing software all together, as one of the primary formats I work with, and will continue to work with, is .MTS. Quite frustrating to be paying $800 a year for a software that has completely just flopped on a project I've been working on for over a year due to a bug that wasn't there in the past and makes absolutely no sense to me.
