After some of the last Fibaro app updates, several people had problems with their FGR-223 (please use the search function: e.g. 1, 2).
And this is the changelog of the last app versions:
With the app version v3.1.8 or v3.1.9 the problems seems to be fixed, but several people had to re-include the devices (also mentioned in the linked posts). So I guess this is the only way to fix it. Also I guess this is not a Z-Wave routing problem.
