I lost all my collections while upgrading the postman. I do not have an account with the postman and I though its just an update, it should not bother much. However, I made an extra copy of Indexdb-folder of the old version just incase. I am trying to import those files but I am not able to. I tried following these steps in the link - https://support.getpostman.com/hc/en-us/articles/360035071313-How-to-recover-my-data-, but dint help much. Could you please help me out on this.
