I'm not sure why voting is closed for this feature - it would surely accumulate hundreds of votes over time.

Adding onto this— very annoying to have to delete all charges and readd them in order to have new entrants to a group added to charges shared with the whole group. It was unclear we had to do this, so half of my group has already settled up and the other half has no expenses. Now I have to delete all transactions in the group, refund 8 separate Venmo transactions, readd all transactions to the group, and then settle up with everyone again.

Well, let me start with this. I was on the same page as you guys were but found a solution.
1.Click on the Pre-existing Expenses
2.Click on the Edit button (Pencil Icon)
3.You'll see an option "Paid by you/anyone and split equally ", click on equally and SELECT "All" > done. It should recalculate the expenses among the group.

Hope that helps :)

Yeah, that's ridiculous. What an obvious bug.

I agree that would be extremely useful. Instead, I added someone to the group, had to delete old expenses then re-enter them in order to include the new person. It can't be that hard to fix.

It's really sad to see 3 different posts about this and still no hints of this being taken into account. With options like Venmo, the power of Splitwise comes with easy management of groups, and this bug makes it close to unusable.

It's not hard to do either, so it just comes off as negligence.

Dear development team,

I understand that this might take a huge change in your data structure or such, but this is a huge thing that would make the app better.

I use the apps for festivals and its becoming cumbersome. Thank you very much.

Kind Regards

Unbelievable that this isn't table stakes for this service. If an expense's "With:" is filled in with the group itself, those expenses should update as new members join the group, not be expanded to be only the members who are in the group at the time the expense is added.

Splitwise please change this

This isn't really a feature request- this is a massive bug with splitwise. The product is close to unuseable for large groups without this. It means we have to manually tell every person in the group to not actually use the app at all to add expenses until every single one of our friends has clicked the link and joined the group.Then we have to have a text or email thread waiting till its confirmed that every single person has joined, which means counting or even starting an excel list if it's a big enough group. Then once every person is joined we tell everyone that now you can add all your expenses. How has this not been fixed?

My use case. Initially, x friends planned for a trip, created a group "Trip" and added expenses. Now, 1 new friend joins the group. There should be a way to automatically split all the expenses in group "Trip" with this newly added person. Basically, all the expenses that existed at the time of adding a new person to the group should be now split with x+1 people instead of x people.

When adding someone to a group late (we had a person come on our trip last minute) you should be prompted asking if you want them added to all of the expenses added prior to them joining. You can have 3 options. 1 - yes, add them to all, 2 - add them to sum (automatically takes you to a screen where all previous expenses live and you can manually add them to some or 3 - no, add them to none.
