Hi everyone
I have been trying to get the OTAA done perfectly , and this forum has helped a lot in the purpose.
Thanks for that 
The question is
What is the best practice for OTAA devices if there are 20 devices booting at the same time and asking for a join request on TTN Gateway?
Many a times . the join get accepted , but the data doesn’t make it through for some applications.
What can be the possible solution for this?
Thanks
