@mallenexpensify FYI I haven't added the External label as I wasn't 100% sure about this issue. Please take a look and add the label if you agree it's a bug and can be handled by external contributors

Weird QA is able to repro. I'm not on an iphone 15 via Browserstack, nor on my iPhone X. ¯_(ツ)_/¯
@rojiphil can you test?

[mallenexpensify]

@rojiphil , plz test and let me know if you can repro

[rojiphil]

@mallenexpensify I can reproduce this on iOS 15.5 (iPhone 13 Pro) simulator.
Here is a test video for the same.

Current assignee @rojiphil is eligible for the External assigner, not assigning anyone new.

[mallenexpensify]

Thanks @rojiphil. d'oh, it's iOS 15, NOT iPhone 15.
I was able to reproduce on iPhone 13, v15.6

Made it External, seems like something a contributor could work on. Let me know if you disagree

[thienlnam]

Is this only failing on a simulator, or actual devices as well?

Asking because this seems to work fine on my iPhone 15 | 17.5.1 | v1.4.76-7

[mallenexpensify]

Damn you Jack, making me do more testing.
I was able to repro the bug on iPhone 14 Pro v16.3, I was not able to repro the bug on my phone 17.5.1 nor via Browserstack with an iPhone 15, v17.5. So there's something going on between the older and newest versions. I'm going to post internally and remove Help Wanted for now.

[melvin-bot]

@rojiphil, @mallenexpensify Eep! 4 days overdue now. Issues have feelings too...

[mallenexpensify]

Shared in #react-native-live-markdown , an agency dev might pick up soon. Adding to #vip-vsb since it doesn't have to do with expenses and markdown isn't mentioned on the roadmap doc
