Eufy indoor 2k showing thumbnails from earlier notifications

This problem has occurred twice so far.

Usually there is a thumbnail photo of the person with person notifications. Works well

Twice this week, thumbnails from earlier notifications have been shown. Now cannot trust the thumbail to be correct

This tells me 2 things:
Eufy is reusing older thumbnails on the camera OR is keeping thumbnails on its backend server and re-using them

Is this a bug or feature? I would prefer thumbnail to be missing than inaccurate

I have been seeing the same issue for months. Only repose from support is they are looking into it.
