I put my computer to sleep on the evening of the 17th the Speed dial icons were there, woke it up the morning of the 18th the Speed dial icons were gone, the version is 64.0.3417.61 so it must have just updated but I don't know when.
Yes I use Opera Sync
No I don't use any third party utilities like CCleaner, these cause more issues than they solve.
The profile path is still correct
They were not under bookmarks or in the trash
I backup my computer weekly so I have the complete profile folder from last Sunday, I closed Opera and copied the Bookmarks and Bookmarks Extra files from my backup to the profile folder, opened Opera again but no Speed dial items were there, how do I restore these?
I don't know, but it doesn't matter. It is important that the problem disappears after this change.
NZXT didn't explain it to me either.
I bet on errors in the program code.
Anyway, that's enough for me because it solves this problem and I don't need an explanation.
@bartelsandreas Since Opera Mini for IOS seems to no longer is being developed, I don't really think they will fix anything.
But you probably should try to ask in the Mobile blog or in the Opera Mini for IOS section of the forum.
