No. No one knows for sure all the details, but they are switching shippers from Expansys. My best guess (and it is just a guess) is that although they had a contract with Expansys to ship, the phones were so late, with prices having been driven up during the pandemic, that Expansys insisted on more money than the contract called for. We don't know if that was a breech of contract by Expansys or if there was a clause allowing that under "dire circumstances" or whether there was a disagreement on what was allowable. Who knows what the legal challenges are here.
So it will take time.
