That was my issue - I effectively had to babysit the charge and keep resting the RCBO

I liaised with the installers as the RCBO comes under their remit for warranty etc. Hypervolt dialled in to my system and could see no fault/issues so it suggested it had to be something else. The installers duly tested it then came back after it continued to happen and replaced it - no issues (so far!) since.... Maybe go back to the installers and request they swap it out for you.
Note I've now a new 12 month warranty on the RCBO
