This is a known user misunderstanding, but don't worry, everything is still there and accessible!
First of all, be sure the Store and the content are actually still there!
In case you are logging in, you cannot find or manage your Store as a different account opens up; it's most likely that you logged in the wrong way.
As an example, if you logged in with Google the first time, you need to keep logging in with Google!
If you are trying to log in to your Store with your email in the email box, even if the same one used by Google, it will be assigned to a new ProMeet Store.
Logging in with Google is different than logging in with your email, even if the same! This, as Google is a service, while the email login is a passwordless process held by Web3 security.
In case you need more help, please open a Support Ticket request, and our staff will reach out to you as soon as possible.
