What is even an APTicket?
Well, the APTicket is what people usually call an SHSH Blob. SHSH are no longer in use but people kept calling APTickets this way because the term was much better known. Starting from iOS 5, Apple replaced the old SHSH blobs with the APTickets. 64-Bit devices always used them. In TSS Saver, you actually save an APTicket, not an SHSH Blob.
If you missed the window when the iOS version you wanna downgrade to in the future was signed, you can still dump the APTicket (SHSH Blob) from the device itself. However, there are some caveats when using this method. The APticket you dump from the device doesn't contain a nonce generator. There is some misinformation spread online that the dumped APtickets are not valid. Actually, they are. You can even check that using img4tool. The problem is that, for the moment, there is no program one can use with these APTickets, but that doesn't mean the situation can't change in the future.
Although you can't use the dumped APTicket like you use a saved SHSH blob in FutureRestore for the moment, in the future these tickets might be very useful. It is worth saving them, especially since the tools used to do so doesn't require the device to be jailbroken.
