Your phone is "not compatible at this time" because Visible blacklisted it this year after they stopped selling the Moto G Power (2021) and started selling the functionally identical Moto G Power (2022).
Visible is simply checking the IMEI to see if the model is on their whitelist. (A very short list indeed.) If it's whitelisted, they send you to https://www.visible.com/compatibility-locked ("Boom. Your phone is compatible. Is your phone paid off and unlocked from your carrier?") which sports a pair of idjot buttons - click "Yes" to see "buy SIM now", "No" for "pay off the phone first, duh".
I bought a Moto G Power (2021) from Visible itself a year ago. Today it's "not compatible at this time" even though it's still working on Visible. However, this guy's Moto G Power (2021), also from Visible, was blacklisted after he replaced the SIM card on the advice of Visible ("Sorry, sucks to be you" they said, and sold him a new phone), and if you check a Moto G Power (2022) or a Moto G Pure IMEI you'll find that both are "not compatible at this time" even though Visible currently sells both phones and both work just fine on parent Verizon.
Basically, Visible is committed to Pixel and iPhone. Others, not so much. Also FYI, it took me a week back and forth with Visible to get voice service after receiving my phone+SIM from them. Visible blamed Verizon, Verizon blamed Visible, then one morning the phone was automagically acceptable to the network. ("Sorry, sucks to be you.")
