hi !! i had this same exact issue with mine. my CA had me take my straps to the LV repair store at my mall, and they sewed it back together in an hour (easy fix) - very convenient. i’m unsure where you’re located and/or if you have a repair location nearby, so they probably will send in just your straps for repair. important to note based off my experience - i would have them sew all 4 tightly together. when i brought mine in, only one of them had come apart, and i asked them to also sew the remaining 3 together tightly so that it wouldn’t happen again in the future / so i wouldn’t have to come back again, and they said no, that they couldn’t because nothing was technically wrong with them at the time.. which is frustrating and guess what, few weeks later it happened to 2 more, so finally then they agreed to sew tightly all 4 of them for me. so i would request the same for yours, especially if they’re going to ship it for repair, cause that’s frustrating if it’ll happen again and you have to wait for it to be sent in. ALSO, i did ask for new straps from a different PSM if they could do that for me rather than fix the one i JUST bought, but they didn’t allow that either, they said they would have to exchange the entire bag if that’s what i wanted to do - just in case you were thinking of that option.
