There were two sources of the messages received by Shane.
One was his family's group chat, where even his father was invited to when Shane hadn't been around. While the other source was the Elus-merchant from whom he received notifications telling him that the crystal packaged had been received.
The notifications about the elemental crystal packages were useless to him. He could also look at his finances in order to estimate his earnings. As such, Shane was more interested in the group chat.
He hoped that Uncle Lars would share some information about the RadiantRing beast tide, once he received the report.
Additionally, it was likely that Uncle Lars would start to brag about Aisha because he had raised her after her parents' death. Lars thought of himself as her real father, even if he wasn't.
