I use several Google Calendars, some I am the primary owner and share with others. Some are shared with me.

All of them no longer show dates older than about 30 days. They still show up on the website, they just don't sync on the phone.

All sync settings are enabled, I have successfully created a new event on the web and it shows up on the phone, I deleted the new event on the phone and that synced with the web...

I tried deleting cache and data, that didn't fix it.

I did A FDR today, including formatting the internal storage.

Now my primary calendar (which I had renamed) now is titled after my google account / email address. I've tried renaming it online and it will not stick.

anyone else having issues? Over at the Google Groups page for Google calendar this seems to be an issue for a number of users.
