Reliable sharing Sharing the ZIP package, PDF report, CSV export and receipt photos works again, including on the latest system versions. You approve what you see If the other parent changed an expense in the meantime, the app lets you know and loads its current version before you approve it. Receipt in another currency When a receipt is in a different currency than the case, the amount is not pre-filled and the app points out the difference. A complete package for your lawyer or the court Every receipt in the ZIP package is checked against its checksum, and the manifest shows for each file whether it is intact. An incomplete package is clearly marked. Your records stay complete If the other parent deletes their account, the shared case stays complete for you — expenses, receipts, approvals and settlements — and you can still view and export it. Fixes The automatic approval period now runs from the last change to an expense. If data cannot be refreshed, the app clearly says so. Sync is reliable even with a long expense history.
