Error 500 re-installing apps after a backup/restore

Hi,
we have an issue on App installation after a backup/restore:
During a trial of the BigPicture App from the marketplace, we did a backup/restore of the whole account. Mistakenly we clicked to overwrite the user information during restore.

Hi @Felix_sw,

Welcome to the community!

This might be caused with the differentiating clientKey, app user, etc. Might be worth contacting the app vendor and have your site’s info removed or refreshed. Issue on import/export can be found here: Log in with Atlassian account, [ACJIRA-1681] - Ecosystem Jira
