Blurry UMG in IOS IPA

Hey Guys ,
Iam Having an issue with the IOS Deveopment , the app is working fine and we have developed an android version from it and everythng looks fine , but when we comes to the IOS development , All the UMG is kind of blurry and have Zig Zag lines although we havenot changed anythng in the Project .
Umg having UI as texture group .

I dont know what settings should effects this .


This is the issue , we are facing , we have done everythng we could do with AntiAliasing , But the Meshes used in the app looks just fine but . UI has no effect .

For the update , we have used the same images from this project and runs them in a new project and made a ipa which gave us clear images , something is wrong with this project , when we uploaded the new images and used them as UI they came blurry as well.
