Ipa file only installs on some iOS devices

I'm facing this issue where my .ipa file installs and runs perfectly on some physical iOS devices. It however, just remains darkened (the logo) after installing on some iOS devices. Now, I've checked the architecture and the build covers all the necessary architectures. I've checked the min sdk too and it more than covers what I need. So I for one am baffled as to why my flutter application only runs on certain iPhones (physical). It runs on all simulators tho.

Photo of darkened logo:

What happened was it became dark and started installing like any iOS app would but after installing, it just remained darkened and was not-clickable. I'm using diawi to generate the link to help the iPhones to download the ipa.

Does anyone know what might be a potential cause for this ?

Solution

There should be few reasons where ipa file should not work on few devices where it works on other ones. Here is the listed below :

Device in which you are trying to install, UDID is not added to the provisioning profile
Link you created for ipa file installation gets corrupted
Site which are using for creating iPa installation link contains installation limits
Installation link gets expired after few days due to free version you are using

Suggestions :

If you are using http://diawi.com try it with Login. So it will give you more time before expiration of the link
Try https://www.installonair.com for making links for installation. Its damn easy to use & works well.

Hope this helps everyone.
