Letters / Apology letter for being late in submission [3]

I was unable to authenticate my degree and transcript in time

I am applying to a university and they asked me to authenticate my degree and transcript at the consulate, but due to the coronavirus epidemic and the social distancing order, I was unable to do it on time. Thus, I want to write an Apology letter for being late in submission. Because English is not my native language, so can you read it and give me a comment so I can improve it?

I am writing this letter to formally apologize for the late submission of my authenticated degree and transcript which was supposed to be due on Apr.30th, 2020.

I sincerely express my apology for the incurred tardy submission of the authenticated diploma and transcript. I understand that this is a mandatory requirement if I want to apply to your university. I have tried my best to prepare all the required documents fully and according to the requirements of the university. However, I did not anticipate the outbreak of Covid -19 and it affected my plans. I am currently in ..., about 200 km from ....where the Taipei Economic and Cultural Office located. With the current epidemic situation, I was not allowed to go there. I will authenticate my degree and transcript as soon as the social distancing order ends and I am allowed to go to .... I hope this mistake will not affect the university's consideration of my application.

Respectfully yours,
