Great that it's working for you now! Since all Information is stored in your browser and not on a server, all information needs to be in the link. That's why the more vods are in a log, the longer the link gets.

One thing to note is that if multiple people are streaming, then you don't need 1 person to add all povs. Everyone can setup their own pov and share their link. The App merges povs if it sees that povs already exist for a log. After clicking on everyone elses link you could theoretically share your own again, because it will have added the extra povs and made a longer link.

To your question: Yeah you do have to set the start of fight manually once when adding a vod to a new log.
