Updates april 2025

Verbeteringen

  • When a general contractor rejects a subcontractor in Publications, the subcontractor can view the rejection notice in the app as well as in the email they receive afterward.
  • We've made publishing faster for general contractors. Where before you sometimes had to wait a while, now it goes a lot smoother.
  • Booster packages are now easier to find in the advertising section for subcontractors.

Bugfixes

  • We fixed a bug for main contractors where the navigation bar on the left side sometimes did not display properly.

  • Fixed a problem on the communication page for general contractors. The date picker in the ‘receive quote’ column would sometimes fall off the screen, making it difficult to select a date. This has now been fixed.

  • We fixed a bug where files could not be downloaded from the prime contractor's documents page.
