This has been discussed recently with the ApexFlex ( very physically similar )
it’s only a short thread
It could still be some swelling causing the lack of vible blinky
Is it HF xLED or LF?
What are you using to light it up?
Have you tried it in a dark room?
but it sounds like it may be too deep.
If you are going to remove it, there are a couple of options you have.
Since you are using an installer, if they have an autoclave, this would problem be your “best” option.
The palm is not really a reccomended install location
BUT it has been done successfully before.
This would be best to discuss with your installer.
