School not receiving official transcripts?

Hi, i’m transferring colleges and my new college requested a copy of my high school transcript and my current college transcript. I mailed both out about a week and a half ago. The online admissions portal still says they haven’t been received. They were only letters, shouldn’t take a week and a half. I had also ordered a copy of an official transcript for myself and it arrived in 2 days. I’m worried they got lost in the mail, but since it’s both of them and they were both mailed from different locations i’m less inclined to believe that.

Has anyone else had this? Do you think I should contact the college asking if they’ve received them?

Sometimes it takes a while to update the portals. If it isn’t there by the end of the week you might want to call and check.
