I'm running the newest IOS 18 beta 4 software on my iPhone 15 Base Model and the first thing is that my emojis are very random I've seen other posts about it, otherwise, they are not changing even though I'm repetitively using other ones to mask what it looks like default ones I the new update, adding on my phone is super glitchy, you could say buggy, I haven't had it feel like that in a long time, with saying I download all the new firmware including betas on all my apple devices, and well there hasn't been a problem until now otherwise I love the latest beta features that apple has presented and I look forward to more.

(Please excuse I didn't know what topic to put this on)
The Developer Forums aren't really the right place to raise bugs in a new version of an OS. Apple's engineers aren't reading through these pages waiting to see if anyone's found a bug before they fix it.
These forums are for third-party developers writing apps for Apple's platforms to discuss issues with their code.
You need to raise each issue you find separately at https://www.apple.com/feedback/ You can post the FB numbers here if you want, so that others can link to them.
