Where did you get that list? If the list you’re showing matches the TTN documentation, then: yes, of course, so RX2 will be using 505.3 SF12BW125, like you can tell from your own screenshot below. If your list is different, well, then TTN is not using that. You’re the only one having problems with the devices and gateways you don’t want to give us any details about. You might want to try joining at a better data rate (lower SF). The problem is in your secret setup.

Following the standard, that’s 1 second for RX1 and 2 seconds for RX2, except for an OTAA Join Accept, for which it is 5 seconds for RX1 and 6 seconds for RX2. If you read other topics about that then you’ll see that the 5 seconds in your screenshot from one of your many other posts is to be expected for RX2, if that’s what you’re wondering about. See Join Accept transmitted after 4 or 5 seconds, instead of 5 or 6?
That’s all we can tell from the little details you keep giving us.
So, why are you asking about the frequency plans and RX2? Apparently you suspect something is wrong, so: why not share those thoughts instead of only asking about some (possibly) related details? If you want proper help then, rather than posting the same things every few days, please explain where you got the information and why you’re asking these things.
Like I linked to earlier: devices not receiving the Join Accepts has been discussed many times before, and asking again is useless. If you want help for your specific case, then you’ll need to give us a lot more details 1) about everything that once worked and everything that still works, 2) about what you tried in the past three weeks, 3) about all your hardware, and 4) about your setup in TTN Console, for applications (including the selected handler), devices, and gateways (including the selected router).
