TL;DR Version: On slack, is it not possible, for a workspace member (not a workspace owner or admin) to update their email to one that belonged to a former member who deactivated their account?
In other words, are the emails associated w/ deactivated accounts added to a sort of "blacklist"?
The owner sent me 2 invites (the initial invite went to an unpreferred email) & despite unknowingly joining the workspace via the unprefferred email on my desktop, I did some things that I'm proud of & want to keep under my name. A couple days later, I signed into the workspace using the preferred invite on my phone & after noticing that my joined channels & direct messages were missing (& that there were 2 members w/ my name now), my mistake was realized.
I deactivated the account on my phone (preferred email but undesired account progress), waited a while, then on desktop (unpreferred email but desired account progress) I chose "Sign out all other sessions", attempted to update email to the preferred one, but received the following error: "That email address is being used by another account". Intended functionality or a bug?
