Costales … If that was your issue on the Solus tracker about the calendar this is your solution.
N.b. all applets via budgie welcome is not an upstream issue and should not be raised there. Budgie welcome applets are from third party developers. All the links for where to raise issues for those applets are available from where you install the applets.
Edit
Please ignore… That was another user who raise this. Sorry about that!!
