Well Opera, I give up ....
I have been an Opera user since a few days after it was released to the U.S. I have sung your praises on numerous occasions and even stuck with you through the move to Chromium (not a good move IMHO). But these latest problems with profile migration are killing me!
I went through all the pains these last few releases, but finally had 102.0.4880.29 working correctly. Then when I updated from .29 to .33 nothing migrated, so I followed the instructions about copying Default data over. That worked good for a few days, and now I saw .40 released. As soon as I upgraded - Bam! - no profile migration. So I went back to the blog post instructions for moving profile data, but this time it didn't work correctly. So no choice but to roll back to Version 101.
So now I have officially rolled back to 101.04843.58 and have all my data. I have synched my Opera account to make sure it all goes to the cloud, but as you know that doesn't capture everything. I have also deleted "opera_gx_splash.exe" to get rid of that annoying startup screen. It looks like I am stuck using 101 for a long time.
Even this one still has issues: "O" Menu button is not rendered correctly, Minimize/Maximize buttons do not work in Win10, you can't drag and drop bookmarks into folders, and a few other things. I have been living with these since they were just inconveniences, but how can you upgrade from 102.xxx.29 to .33 to .40 (all within version 102) and still not have profile migration working correctly. Once you have moved profile data shouldn't all subsequent 102 versions read from the same folders?!?!
