Right on schedule, Apple has released iOS 13 public beta 4 and iPadOS 13 public beta 4 following the recent release of iOS 13 developer beta 5 and the corresponding iPadOS version. Apple always releases public betas after developer betas to allow for the discovery of any major issues. Apparently, no major issues were discovered because, well, here we are. The new public beta is identical to the developer beta that was just rolled out though, and it irons out a bunch of wrinkles that have probably been driving you crazy. In other words, hurry up and install it right now.
