Users are reporting a bug on iOS where the reply box doesn’t allow scrolling down when typing long messages — it reverts to the top. Gatroe, using an iPhone SE on iOS 15.3, confirmed the issue persisted even after updating. pmusaraj suggested checking Safari’s Experimental Features, specifically the Visual Viewport API, which Gatroe had disabled. After enabling it, the issue was resolved Gatroe. The fix suggests the problem stems from a Safari setting meant for testing, not a system or app bug. pmusaraj noted the setting is enabled by default and disabling it can cause composer issues. The issue appears isolated to mobile Safari on certain iOS versions, particularly affecting devices like the iPhone SE. Gatroe shared a video and screenshot to illustrate the problem, and confirmed resolution after enabling the Visual Viewport API. This workaround restores proper scrolling behavior in the reply box without requiring device or OS changes. The thread highlights how experimental browser settings can unintentionally break core functionality, and how quick community support can resolve such issues.
Anyone having an issue with the size of the reply box on iOS? When I have a message that is long, I’m unable to scroll down to see what I’m typing. It just reverts back to the top of the message. I thought it was because my phone didn’t have the latest update, but I went to iOS 15 last week and I’m still having the issue. Seems to only be happening on mobile.
In order for me to post this, I had to request desktop website on my iPhone
Are you up to date with the latest iOS 15 version? There are some Safari issues on iOS 15.0 and 14.1, the bottom status bar had a height calculation issue that was fixed in 15.2.
See if updating iOS helps. If not, please also let me know the model of your device.
Yes I am up to date.
iPhone SE
iOS 15.3
I don’t have an SE and can’t reproduce in the iPhone SE simulator.
Have you disabled the Visual Viewport API in Safari’s Advanced > Experimental Features by any chance?
Yes that was already disabled when I just went to check it out.
Go ahead and enable it, it should fix your composer issues. By default, that setting is enabled in Safari, it’s there just for testing purposes.
This worked. Appreciated the help and the quick responses!
