Safari tabs auto closing instead of navigating to page
This was a problem a year or so ago and now starting about 6 weeks ago after an iOS update this has started happening on a regular basis again.
Basically I type in a web address, press enter, Safari takes several seconds to respond and then the tab closes. Simultaneous to this problem starting the browser began lagging again, so even when it does work it takes numerous seconds to navigate to a page despite having a solid internet connection with 70M service.
Has anyone figured out a fix to this browser issue? It's highly annoying and makes using Safari a bit tedious when pages are closing or taking long periods of time to load.
