Proposal

Please re-state the problem that we are trying to solve in this issue.

User avatars are swapped in IOU preview when splitting bills

What is the root cause of that problem?

When splitting a bill, users are added in order they are selected. In that order, they are displayed in MoneyRequestPreview. But the SplitBillAndOpenReport API returns sorted particiapantAccountIDs as you can see below

This is the root cause

What changes do you think we should make in order to solve the problem?

We can show the participants avatars sorted by its accountID or name(login) In MoneyRequestPreview
Update

App/src/components/ReportActionItem/MoneyRequestPreview.js

Line 154 in 4952c39

const participantAvatars = OptionsListUtils.getAvatarsForAccountIDs(participantAccountIDs, props.personalDetails);

to

    const participantAvatars = OptionsListUtils.getAvatarsForAccountIDs(participantAccountIDs, props.personalDetails);
    const sortedParticipantAvatars = _.sortBy(participantAvatars, (avatar) => avatar.name);
    // const sortedParticipantAvatars = _.sortBy(participantAvatars, (avatar) => avatar.id);

And use sortedParticipantAvatars instead of participantAvatars

What alternative solutions did you explore? (Optional)

[trjExpensify]

Very interesting! It's pretty minor, but I agree it's a little jarring to see the switch around because of the default avatars changing completely. Is it not possible to keep the same selected order on the split preview?

@trjExpensify It's definitely possible but we'll need to change this from the backend then. I think its better to standardise this by sorting the results. As such, what @s-alves10 proposed above looks like a better solution IMO.
