All encodeID are shared by all PicSee users. So, once PicSee users have already set up before, whether the link has been deleted or expired, other people still cannot use this encodeID again.
1. Try changing the encodeID of original link
For example, you want to use “2022_activity” as your encodeID.
Find the original link which used “2022_activity” and you can add other characters like numbers or a hyphen like “2022_activity-1”.
2. Go back to the link you want to change.
Go back to the link you want to change and you can change it into “2022_activity”.
