Broadlink devices keep disappearing in IHC

I added the rm pro to the ihc and some light switches. Now they have all disappeared from the app. Third time this has happened.

I can add the rm pro back in but the light switch device icon is no longer there.

This must be the most unreliable app I have used. There seems to be a new issue every day. Broadlink really need to sort their shit out !!!

I use e-control to learn and export the codes to HASS. It works well.
