OFT's are very low stock to backordered for some of their supported platforms during the pandemic. Keep contacting them, maybe try facebook comment or direct message.

These days if you need it quick then it's best to buy used. Maybe join your local ft86 facebook group and see if there is one for sale. There should be something regularly, check the classifieds here as well. The response times from OpenFlash or Shiv have slowed down quite a bit since they’re supporting other platforms. You'll definitely be waiting, keep pushing for an update or cancel order if you must.
