You're not alone. Google just "redesigned" the Play Store website, and it's an absolute mess. The site was just fine the way it was. Loaded up quickly and smoothly, easy to navigate, and so on. Again, it's now an absolute mess.
Last night I did a reset on my tablet, rooted, etc., so I'm just finishing setting everything up. Last thing to do is set up bookmarks in the stock browser so I can use my bookmark widget (Android Pro Widgets).
Trying to save the Play Store site as a bookmark is a nightmare. I finally managed to do it after jerking around with it for a good 20 minutes. Again, this was with the stock browser. I use Dolphin as my default browser, and I haven't tried with it yet.
The new site takes forever to load, locks up my whole tablet and then crashes to the desktop.
My tablet runs like a dream. But I try a LOT of apps, etc., so it was time for a reset. I feel it's a good thing to do after so many install/uninstall of dozens and dozens of apps, updates to apps, etc. Setting up my bookmarks is the last thing I have to do. Everything runs smooth as silk. The ONLY thing I'm having an issue with is the Play Store web site.
So, as I wrote way back at the beginning of this rant
, you're not alone.
Hopefully Google will get it sorted out quickly.
