To make the program count the days for parcels WITHOUT tracks, you should manually add a custom event with the desired date, the counter will start from the date of this event.
That message means that the track number of the shipment did not match to UPU S10 standard, all the track number (identifiers) of international parcels and mails should correspond to it.
There is a possibility that the track is wrong or false.
However, the track may be tracked normally. But you should give a maximum attention to parcel with such track, at least, until first event for track.
The best way to tell us about bugs and issues in App is to send an e-mail and describe the problem. Do not forget to specify the postal track number and list the post services if the error occurs for a specific track.
Unfortunately, more and more post services add Captcha on they tracking sites. If captcha can not be automatically recognized by the program, the user is prompted to enter it manually. At the moment, there are several such services (china, fj_freipost, etc.). So, when you check each track on these services, you will be prompted to enter the captcha manually.
If you do not want to see CAPTCHA pop up window, you have to disable these services in the track properties window.
Also in the App there is the option "Skip services with CAPTCHA", which allows you to disable the poll of the services that require manual enter of CAPTCHA in automatic or manual modes.
