I didn’t know the email with which a snap was created. Through another email I request creating a snap with the same name. That prompted an option to dispute the name which I did. Support person said that they cannot tell the email but they send an email to both addresses so I could remember it and could ask to restart password. After logging in to the forgotten account, I added my other account as a collaborator and told the support person that all is good. Then, the support person revoked my dispute and now the other account doesn’t have access to the snap and I cannot add it.
Could someone help? The snap is Install homehero on Linux | Snap Store.
