OnePlus 12 - Verizon - no 5G UW after 0.604 update

My wife and I both have the OnePlus 12. Both on same Verizon plan (unlimited data). My phone updated a couple days ago to "Version number" ending in 604. Wife's phone still on previous version.

After update to 604 my phone no longer displays 5G UW in areas it used to. Holding both our phones next to each other, my wife's phone still displays 5G UW and also scores 2x-3x higher in internet speed tests. What is happening here?? Please help.

6/7/24 edit: After update 0.802 I'm seeing 5G UW displayed again. My wife's phone never stopped displaying it. ¯\_(ツ)_/¯
