Why do my texts keep switching between RCS and SMS on iPhone?

I’m trying to talk to someone over text who has an android, but every text i send is being sent as SMS and all of theirs are being sent as RCS. It keeps flipping back and forth and it’s annoying.

This is happening to me as well since the ios 18.1.1 update last friday. Sometimes I send a msg and it goes by RCS but mostly its going by sms. My boyfriend's msg are coming to me as rcs but when i reply it sends as sms. Prior to the ios update everything was by RCS both ways with zero issues. I wish I hadn't updated the ios...Apple needs to fix this crap

I am having a similar issue with a seemingly different cause. I’m on an iPhone 16, and my friend has a Google Pixel. RCS between our phones has been very reliable, but just today I had my phone send a picture as an SMS because it had failed to send as RCS, and now it won’t stop using SMS for specifically that thread despite the fact that RCS works fine for other android owners I text. I can’t figure out how to fix this, as there is no obvious way to me to fix it for a single thread, and Googling it isn‘t helping
