Is it normal for your first business to take a lot of time to launch due to miscommunication? I will not promote

I came up with a business idea almost 2 years ago, left my Job last year in May. Was on a sabbatical for 5 months since the Job I left was too taxing on me health-wise. I have a non-technical background so last year in October I met 2 people to partner with who are Full Stack Developer, one of my partner had a business in the past which failed due to COVID and the other is a good friend of mine. Note : The 2 partners have a Job, I don't so we only get weekends to discuss on various topics. They (one who had a failed business) suggested that I should start with Market Research which took me 3 months, this helped me realise how market in different locations work. Then I started with creating a Mock-up for the App which they suggested I should take a lead on. Now, there is a lot of miscommunication which is building up around us since they talk in technical language, it is all new to me and I'm hesitating to ask for help. It feels like I am not able to take a lead in this entire partnership or should I lay low since this is my first business. I have a business idea but I am not aware how to take it further, I'm glad my partner is taking the lead here but it is frustrating to not know how to take the next step! Is it because of my Ego which is making me think like this? Would like to know how was it for you while starting a business? Is this entire thing normal?
