Hello,
First of all thank you so much for this library to be available for everyone! I use T-Deck plus (with SC126x radio) in combination with Helium-IoT Console and see that I receive a JoinRequest and JoinAccept. The Issue is that I don't receive any data from the Helium server (from 100 tries I was only able to get it once, even at different locations). I have no clock jitter and set the scanguard to 50. To avoid throttling i disabled the dutyCycle checks.
I receive the following message: JoinAccept reply length mismatch, expected 33B got 0B with error code -1102.

To Reproduce I used code from https://github.com/Xinyuan-LilyGO/T-Deck but removed Radiolib completely and replaced it with the latest version https://github.com/jgromes/RadioLib version 7.1.0

Expected behavior When the helium server receives a JoinRequest and sends a JoinAccept I would expect the data to be received from my T-Deck plus device.
