Download da GiuntiTVP

[stepersy]

Ciao! Innanzitutto grazie mille per lo stupendo lavoro che stai facendo! Ho visto che è stata aggiunta la possibilità di scaricare da GiuntiTVP mediante One Shot Link. Come si usa? Ho provato a incollare il link di un mio libro (https://mydbook.giuntitvp.it/app/books/GIAC67_G6760798D/pdfParts?prependCollection=BL35LIV07_MYDBOOK2019) ma continua a rispondere "Unable to view this publicly. Aborting...". Grazieee :)
