Firstly, welcome back! Sorry you're having some trouble with the app process!
Your intro is here
To explain a bit about E, just filling out the questionnaire alone does not ensure approval. The e-mails are a bit of a reminder to check your introduction thread to interact there if people left replies, as the approvals team expects a certain amount of interaction with you after filling the questionnaire out, to get an idea if you are a fit for the community and if the community is right for you. Just check your intro thread to see if any people have replied to it, answering questions/prompts as needed. This has the added nice effect of letting you dip your toes in and talk to Mentors and sometimes members while applying, which can be useful, considering how big the community here is.
After sufficient interaction and when the approvals team has time, they will make a decision about whether or not you are approved.
Just be yourself and keep an eye out on your thread for questions and interactions! :)
