Only people using iPhone 15 and iPhone 15Pro (don't know about iPhone 15 plus or iPhone 15 pro max) are having problems with my App. All seems fine on 13, 14 and 16 as well as iPad The app is in testflight now. I cannot replicate the issue in MAC via virtual iPhone 15 , 15 plus, pro, or promax. What I see happening - it looks like users are seeing labels disappear, sometimes buttons are disappearing on the 15 pro and 15.
I have an ingredient selection page where you can select the ingredients that you have. These are outlined and grouped to make choosing ingredients intuitive. I have a profile selector where you can choose by flavor, strength, body or mood. At the bottom I have three buttons , button one lets you choose if drinks are sorted or strictly matched. The last button allows the user to see the drinks they can make based on ingredients they have.This is done by matching the ingredients with a locally placed drinks list which contains a drink id, drink name, ingredients and profile information. Clicking the last button opens a flatlist.
Users on iPhone 15 and iPhone 15Pro iOS 18 sometimes experience the three buttons at the bottom being gone altogether. then returning. After clicking the Drinks Available button the button label should change to hide available drinks, but sometimes that label disappears. The drinks flat list has space for many drinks but the labels for those drinks are not present until halfway down the list where one drink shows up.
No other device behaves this way. It might be more common when there are large number of ingredients selected ....e.g., if about 50% of 211 ingredients selected it might be more likely to happen. This needs to be tested to verify,
