If it was not a place with reporting requirements to the DOH (e.g., the VA), the DOH would not have that info and that is what the app searches. But another thing that prevents finding it is if the name reported by the place you were vaccinated does not match the name you registered on Excelsior. It has to be an exact match. The first time I did it, I used the name I use day in and day out, but the drug store filed it using the name as it appears on my insurance card. If all else fails, I would call DOH and see if they can sort it out. Good luck.
