Inconsistent/Unreliable Join Issues

End Devices (Nodes)
7

I was able to join successfully again so I’m fairly certain the EUIs and keys are correct. However the join response is still very unreliable. 80-90% of the time it goes through all 8 channels without successfully connecting. I tried changing the SF to 7 but the console still shows it as 10 until it joins. Then when it joins it drops down to the value I set it to. It’s strange because the example uses the same data rate definition in the join procedure as the tx.

Here’s the data for a successful join if that helps narrow things:
