Looking for feedback on MVP app🚀

We've created an application that gathers and shares referral links. The user traffic is low for now, but in the current development stage, we'd like to focus on user needs. We should have started from that stage, but MVP is already created, and I think based on it will be much easier to explain our idea to the user and create the user persona profile.

We have a few ideas in which direction this app should go.

INFLUENCER PROFILE CONNECTED TO INSTAGRAM ACCOUNT 📸

an influencer can share promo code using our website to extend its potential users. F.e. influencer has 100k followers, our website has 1000k users, so if they put their promo code on our website, they can earn more because more users use their codes. To keep a connection with the influencers' we add the ability to generate a link to the dedicated website with all codes posted by the user, so our influencer can share this link on their Instagram account, in bio or in posts.

USER, WHO SEEKS FOR PROMOTION IF THEY WANT TO BUY SOMETHING ONLINE

whenever they buy online, they seek a promotion to pay less. Because we know that there are many referring systems, promo codes posted by our friends or influencers, we want to use the one to the desired shop, but they don't want to lose our time searching for the code through the network, and they are not able to follow all possible Instagram profiles only to get a promo code. But if someone shares it on a common platform they would love to use it. Win-win relationship. The one who posted earn money for referring, the buyer saves money while buying.

USER, WHO WANTS TO GET EXTRA DISCOUNT, EARN FEW DOLLARS BY REFERRING COMPANIES, BUT THEY ARE NOT INFLUENCERS 🤑

many companies have their referring policies, and there encourage their users to share it with friends or family. So, these users do it, but their range is limited to Facebook or Instagram friends, and it may happen that they don't want/ can't use their referral. So, why don't we give the ability to reach more people?

We also have plans for developing our app by for example: 📈

connecting Instagram account to our app,
implementing browser extension where user can check if in the current site is any discount
notifications systems for influencers, which let them watch which products their competitors advertise(maybe it will be a good idea to also contact with that company and start referring their products, too)

Share your thoughts if it does make sense for you

I would be grateful if you could also answer on few below questions:

Have you ever used promo codes/referral links?
Have you ever shared your own to earn a few bucks?
How have you got it?
Do you use any 'promo-code' website? Which one?
Have you ever struggled while searching for a promo code on Instagram profiles?
Have you ever wondered if onsite is any promo code?
Have you searched for any promo codes?
Would you like to have an extension in a browser that will inform you about any promo codes on the website?
