Fix PWA Web App to "download" it to home screen mobiles (ios and android)

Job ID: 36770744

Budget: $10 – $30 USD

Description:
We recently published a PWA Web App but it still isn't as it should be. We need someone specialized to fix a connection issue thru SSL.

Basically, we have 3 environments in the project:
A: End-user mobile phone
B: An https server where the pwa web app is
c: a rest api server embedded in an arduino box in which are the apis that the pwa accesses

Expectation:
End-user mobile should be able to download the pwa to its home screen (ios and android) and use the application normally (like it would a native one). Of course it's a PWA Web and not a native one. And we also dont need to upload it the Apple and Google Stores.

Sympton/Issue: The mobile user is unable to download the PWA Web App.
