Curious hole/button...

[Jacklind]

Just curious. What's this little white button-thing with a triangle symbol???

[Thommo]

Is that not where the flap connector should be

As far as I know it's where the liquid indicator is placed. The small white piece of paper turns red/pink if exposed to liquids. Might be something else as well, but I'm not sure

Yes, it is where the flap connector is, but I thought that it might be something else too given that there's a small symbol there...
