[Bug] Backup restore messes up all transaction and recurring transactions on multiple devices not syncing correctly

I am using two devices syncing the transactions using the iCloud synchronization. After I changed some of my recurring transactions on one device it did not properly sync to the other device which stilll had the old recurring transactions and synced it back to iCloud. So I created a backup on the main device in flight mode and restored it. After restoring the backup the transactions were correct in the first few seconds but the iCloud synchronization messed up all transactions and removed most of the transactions. To restore the backup correctly, I had to reset the app on both devices, set both devices to flight mode, restore the backup on one device and setup the other device with the iCloud data. Currently it seems to have worked and my transactions are fully restored.
