Recent worksheets and books not shown and not found anymore
this morning I noticed that a serie of recent books and worksheets aren't shown anymore in the overview, neither are they shown in search results. Some of them I had linked in my own website and this link still works, so the files still exist. But when I type the titles of them they're not shown in my search results on the Materials Platform: https://www.geogebra.org/ccambre eg.:
stelling van Morley : https://ggbm.at/TK29NTva
Underwood Dudley : https://ggbm.at/FvFTXxmu
stelling van Marden : https://ggbm.at/rPuhnErB
Today I uploaded some new files and books. The last ones I made are shown, but again the first ones I made today are gone once again.
Can you give a look at this?
