You can sometimes see some transactions with the sign "Pending" next to them. These are transactions which have already been deducted from your bank account but are yet to be posted. These transactions cannot be edited at the moment - you need to wait for them to become posted.
What should you do in case your transactions seem to be pending for a long time?
First thing - check Web App. In case your transactions don't have the "Pending" sign attached to them there anymore, reinstalling the app may help. Make sure that all your manually entered transactions are fully synced between the mobile app and the Web App before reinstalling the app or you may experience data loss.
In case they are in the pending state in the Web App, too, and it has been more than a week, contact us at firstname.lastname@example.org and we'll check what's wrong.
