Everything is working fine after the upgrade, except I can no longer sync Picasa albums. I got to Settings > Accounts & sync > Google > Sync Picasa -- but nothing happens. It won't sync. Any suggestions?
And what is Google Photos? Never saw that one before. I'm not on Google+
Are the Missing albums the indicator you are using to say that Picasa is not synchronizing, or are you going off of last sync time in accounts and sync>google?
Followed this string and found setting for Picasa sync. "deselected" by ICS install and last sync date of 7/31. Once I reselected Picasa sync, my albums were immediately restored to GSII's gallery. Google has released version upgrades of Picasa and Picasa Web Albums within the last few weeks. You might check if the permissions on your albums are correct to allow D/L of photos instead of just links.
@reginold Not sure what you mean by reselecting Picasa. I "tap now to sync" and it doesn't sync. Is there some other place I need to reselect it. Also I haven't changed permissions and I was able to download albums before the ICS update.
When I reviewed my google sync settings after ICS, I found the checkmark next to Picasa "greyed out". I did not change settings, so assume that ICS install must have changed the setting. Once I reselected Picasa sync, checkmark turned green, I could see data transfer between Google servers and my phone for maybe 15 seconds, and about 50 photos were restored in 2 albums - as before in the "gallery". I had wiped the albums from the gallery before installing ICS.
