Currently, the new dashboard created as part of Section Translation includes a banner stating that the "Mobile support is experimental" (T270501). This was added in the early days of the mobile support where many important features were missing (searching, working in multiple sessions etc.). However, the mobile experience is at a point where it can be removed.

This ticket proposes to remove the banner because the new dashboard is more complete as it is getting ready to become the unified dashboard (T353244). In addition, as the new dashboard becomes the only one, it won't be exclusively used on mobile (i.e., the messaging will no longer apply).
