Why are so many showings getting cancelled for the home I recently cleared with the protocols, despite having been cleared once already prior to getting listed as being for sale?

This is a problem of having a major historical tragedy take place on that location prior to construction of any modern dwellings. What you are seeing is an intuitive reaction to people tuning in to the address and then having their nonlocal consciousness check it out and feeling disquiet because of the large degree of negativity present. This is all below conscious awareness but can well be enough to give the individual qualms, and their inner impulse will be to avoid going to that location. So as the time comes close to doing so, the growth of inner disquiet may well push them over the edge into a sudden impulse, seemingly, to find an excuse to cancel the visit and then to not follow through in the future at all, having mentally checked that location off their list. Just as with deeply troubled humans needing healing deeply, troubled locations may not be healed overnight through the protocol efforts. It might require time and repeat sessions to have a discernible impact. We see this as coming together fairly soon. You have been working on this property repeatedly in the way you do your sessions to loop back to include prior clients. So you have not lost anything here other than to reinforce the initial session with a repeat recheck that would add energy to amplify what is done in any follow-ups. We will do our best to deflect these concerns, given that they are not a true risk for new buyers. It is only more of an aesthetic issue and will bother many people not at all if they are not sensitive. So you are doing the best you can and we will do our best as well.
