Hi simarwalia88,
Was your MR through medical clinic? If not then the delay is still not alarming.
If yes, the connect with them and verify the UCI & IME details from them against which they uploaded the reports.
Provided they are also correct, there is really nothing much that you need to worry of. Eventually the 3rd line will be updated.
** In my case, I saw my line not updated for 6 days post test and I called on the 8th day and made sure that they had the right details. Parallel to it, my online status also got added will line 3.
** Might be silly, but clear you cache, use the root link to get into you online application status. Link is below.
Once in, click logout. Clear cache again. Try it again and check.
