My Keychron B1 Pro just arrived, and noticed it drops keystrokes during fast typing, both over Bluetooth and USB-C.

Examples (for context, I use Colemak-DH):

• Typing oin quickly often drops the n
• Typing you quickly often drops the u
• Holding o, then pressing i, then n often results in n not registering
• Holding y, then pressing o, then u often results in u not registering

Karabiner EventViewer does not see the missing key events, so it appears the keyboard itself is not sending them.

One thing worth mentioning is that I also removed and swapped a couple of keycaps, but I didn't have a proper keycap puller or other keyboard tools—just improvised with what I had. Initially I thought I had damaged a key, but after more testing it seems to affect multiple keys.

Is this normal for the B1 Pro due to rollover/matrix limitations, or does it sound like I have a defective unit? Can any B1 Pro owners reproduce these combinations?

Context:
- Not a Colombian citizen
- No overstays / immigration issues
- ~20 days left on current permitted stay (already used prórroga)
- Likely staying long-term

Question:
If I leave Colombia before my stay expires, can re-entry still result in a new 90-day entry period?

Also, does same-day re-entry usually work in practice, or do immigration officers generally expect some minimum time outside the country before returning?

I’m a US citizen currently living in Colombia, but I’m not a Colombian citizen and I don’t currently earn any Colombian-source income.

Is “residente fiscal” still something I need to worry about? At what point does Colombia consider you a tax resident, and would that mean paying taxes to Colombia on worldwide income even if my income is from the US?

DIAN / accountants are telling me one thing, and online sources are telling me another.

Trying to understand how this works before I accidentally create a tax problem for myself.
