This is a rare issue that can happen if there is a problem with your account verification or your phone number registration. It can also happen if there is a network error or a server outage. To fix this issue, you need to check your internet connection and make sure it is stable. You also need to verify your phone number and email address with us and with Poshmark. If you still cannot sign in, please contact our support team for further assistance.
This is another bug that we are aware of and working to fix as soon as possible. It happens when our service sends out offers to likers automatically to increase your sales. Sometimes, the offers are duplicated and sent twice to the same liker. We apologize for the confusion and we appreciate your patience. To fix this issue, you need to cancel the duplicate offer and send a new one with a different amount.
This is not a bug, but a feature that we are using to improve your listing visibility on Poshmark. It happens when our service delists and relists your items automatically to boost their chances of appearing in the “Just In” search filter on Poshmark. This filter is the most used by buyers and it has the stigma of the item having more a chance to sell. Sometimes, the listing titles are changed slightly to avoid copy detection by Poshmark. This does not affect your listing quality or ranking. You do not need to fix this issue, but you can manually edit your listing titles back to their original state if you prefer. In our latest patch, we are giving you the option to modify how titles are altered during the relisting process. You can find it under the “Relists” section of the settings menu.
This is an issue that can happen if you have multiple devices or accounts linked to our service. It can cause problems with your closet activity and performance. To fix this issue, you need to unlink any devices or accounts that you are not using from our service. You also need to refresh your closet in AP and make sure it is registered in only one server.
