I am testing my project and am experiencing heartbeat timeouts on a fairly regular basis (see below). I am using #define BLYNK_HEARTBEAT 300 in my code and that has not changed for quite some time. Prior to the latest library update using this heartbeat interval was working fine. I have only noticed this issue this morning The only changes I am making to my code as I progress is to add additional slave nodes. I can of course adjust my heartbeat but something has changed to cause this issue. Perhaps it is related to issues @Dmytro pointed out in this post?
