Oh man... you have my sympathies it's super frustrating to get application process be hindered by transcript requests, which should be the simplest of all the application components... and 60 days?!? That's insane...
Let's hope that all universities will offer e-transcripts (as well as accepting those) in the next not 20, but 2 years! Glad to hear that everything worked out for you and that you got admitted to your first choice. Congrats!
