Hi @Gordon,
I upgraded two of my Puck from 1v97 to 1v99, uploaded a code and saved it.
1) Device1 does not contain any code, all the times I save the code and restart it the code is missing.
2) Device2 doesn't contained any code for the first 2 saves, after that somehow it succeeded to save it and is working as expected.
Any ideas ?
