iOS 14 includes a number of bug fixes and improvements, such as Dropbox and "OSX Server" in Files App now turned on, the ability to close apps by swiping up on the iPad, etc. In the meanwhile, a list of new bugs is found in the new beta version. Therefore, iOS 15, like earlier iOS 15 Betas, should only be installed on secondary device, but not primary device. If you’ve had enough with the unstable beta version, you can always downgrade it to iOS 10.3 by using Tenorshare ReiBoot, a powerful tool to downgrade iOS 11 without stuck.
