Platform, device and operation system Android Galaxy Note 9, Version 10

What were you expecting to happen, and what actually happened Expecting not to get crazy script/code pop up. Got a gold chest after a Skirmish and was rewarded Jeweled Pants. It had no picture. Went to gear to upgrade And this code popped up. There is still no icon for the pants.
If you are on a console device please feel free to take a photo using another device. Where possible, a video helps us best. Try uploading it to Youtube privately.

How often does this happen? When did it begin happening? just this once so far.
Is this a once-off issue or has it been a consistent issue? Does it only happen in specific circumstances?

Steps to make it happen again will have to wait to see if I can get Jewels Pants
