Thank you very much for that Willian, appreciate it. Out of curiosity, do you know what changes were between the v3.26 to v3.27 (I haven’t been able to find release info)? Wondering if it is worth doing a tear down to direct update it now if the changes are fairly important or wait until next time I do.


The 3.26 to 3.37 update aims to fix some problems related to protocol implementation to work with the last version of our libraries and programs
