If you’re referring to the one-click Mastodon droplet - https://marketplace.digitalocean.com/apps/mastodon
than this is up to the vendor itself.
I believe that a similar question was previously asked in our community in this question:
I will quote the answer provided from Danny here as well:
Thanks for reaching out! We have our partners build their images and submit them via our Marketplace Vendor Portal. From there, we test, approve, list the updated image. Depending on how many updates from vendors we receive, basically how busy things get, testing, approving, and listing an image can take up to a week but are usually completed in a day or two. We appreciate our partners’ patience and understanding that sometimes, it may take longer than a couple of days.
Hope that this helps!
