Unable to answer "Are the pickup times of this collection box still correct?" for https://osm.org/node/1616677507 via StreetComplete 49.2:

The  listed collection times for this posy box are still as printed on the box, but it also has a sticker on it saying "Priority Postbox Saturday & Sunday". I am not sure if this means it is also collected on a Sunday too?
