We have a system which has been running successfully live for many months which submits listings from a proprietary product database. This system allows submission of items with "Featured First" listing, e.g. <GalleryType>Featured</GalleryType>.
This only seems to work now if GalleryDuration is set to Days_7. LifeTime no longer works, nor does Days_30, which we had been previously advised to use in place of LifeTime. Using either of Days_30 or LifeTime gives the error:
21916051: InvalID value for Gallery Duration. (InvalID value provided for Gallery Duration.)
This is impacting our customer's ability to list items and they are understandably frustrated. Can anyone please shed some light on why we are unable to use any duration but 7 days, when it is clearly stated that LifeTime should be supported too?
Any assistance would be greatly appreciated!
