I don't know English, so I used a translation software. Please excuse me.
The verification will be closed in September this time. It's really too fast. After I experienced iOS 26, I found that I couldn't go back to iOS 18.
iOS 26 still has many immature aspects. You can't trap users in an unfinished system.
Look at these two images. It's easy to notice that the background blur effect in the iOS 26 control center appears cheaper compared to the background blur in iOS 18.
It's a pity that the uploaded images have to be compressed, making the differences less obvious in the preview. Besides this, iOS 26 still has many imperfections. For example, when long-pressing the Wi-Fi button, the pop-up Wi-Fi options do not have the liquid glass effect. Additionally, there is a brief color issue after closing this Wi-Fi menu.
I'm not sure if the previous translations fully conveyed the message, but I sincerely hope Apple can temporarily reopen the signing verification for iOS 18 to allow users to downgrade. The current iOS 26 still has many unresolved bugs, and users do not want to use an unfinished system. Please, we are pleading for this.
