I've been licensing images since 2017 but have just recently started to notice previously licensed images disappearing from Adobe Stock and no longer being able to be downloaded. These are still listed in my license history, but can no longer be accessed, and has a message indicating they're unavailable for download.
I expect to be able to use these images for commercial products even though they're no longer available. Some of them have been used already since I've been at this since 2017. If they have been removed for some reason that makes the license no longer valid, I should be informed of why and whether I need to take any action regarding any products that already use the licenses. Additionally, if I can no longer use the licenses, the credit should be returned to me so that I can license other images instead.
These are the affected images:

There are several reasons that may make the assets unavailable for licensing.
A subsequent quality check found issues with the file.
The contributor deleted the asset from his portfolio or the contributor asked to delete his account.
The portfolio got blocked because of illegal or improper activities of the account holder.
The contributor stole assets from a different source and published them under his own name. The account got subsequently blocked and the assets are no more available for sale.
1, 2 and 3 are not critical for you, as the contributor's agreement with Adobe give you the possibility to continue to use the asset. I would guess that the big majority of cases are covered by these cases.
As for the forth case, I suppose that Adobe takes it's responsibility and informs licencees of the possible trouble.
