NB: Lemmy.world is having ongoing federation delays (and has been for several months). Neither upvotes or replies from lemmy.world are being received by my instance for around 1-2 weeks. I promise I'm not just ignoring any responses
I clicked the provided link, long pressed the link button, then clicked the address on the popup which got the thread to load. After finding the comment myself, I hit Copy Link in boost and got a db0 link out of it, which is odd.
Both long press and tapping the address in the popupp, and clicking the link you posted leads me to the same thing as in the screenshot I posted.
I am on boost 1.0.12 (15) from GPlay
Edit: I can open them /c/ tapping its name in the post and find the May 19 thread, and open it. No /u/Baku, no "calculator" to be found. Can do a screen record if wanted .
