App icon is no longer displaying correctly

Describe the bug:
My App icon no longer appears correctly on:
1: Phone as a DL’ed icon
2: While loading app
This has been a recent change in the past week or so. Icon has been uploaded on my app for a year, with no previous display issues. It is a JPG.

Expected Behaviour:
There should be no gaps/spaces marked around icon, and during load process

How to replicate:
Go to app https://ververy.app, DL app to home screen
