MEMORY_BUSYhappens when something is happening to the variable store which keeps it busy (that usually means garbage collection) and a new variable is requested from inside an interrupt.That should be extremely rare especially on Bangle.js 2, so it'd be great if you could find a way to reliably reproduce it. It's possible you have some app that is forcing a garbage collect which is making it more of a problem though? On Bangle.js 2 GC passes should be super rare given the amount of RAM available.
