Pre-conversion, my Agilekeychain vault had maybe a 15 top-level folders with some sub-folders as deep as four or five levels. Via Dropbox sync, the folder structure displayed correctly on Windows (184.108.40.2066 (thank you for not forcing use of 1Password.com accounts)) and Android (something pre-7.0.4).
Upon updating my 1Password Professional subscription Android App to 7.0.4 on C. 9/14/2018 I was offered and accepted conversion from agilekeychain to opvault on my SM-G960U at Android 8.0.0 w/ sec patch level 8/1/2018. Note: updated to 7.0.5 as of 2-seconds ago and problem remains.
1Pwd for Android no longer has folder structure and AFAIK only uses tags (N.B. I hate tags compared to folders; how about 'both,' like 1Pwd used to have?).
1Pwd for Windows, after selecting the new OPVault, no longer has my custom folder structures; only "All," "Unassigned," and "Trash." The total number of items appears to be roughly correct at just over 600.
Everything else, i.e. other feature I regularly use, seems to be working correctly.
Return of my old folder structure in 1Pwd for Windows (since this is the Windows forum), without having to manually rearrange 600+ items from memory.
Probably something I did but I'd prefer your guidance if you recommend a vault re-do. I am hamstrung for now, but without my 1Pwd... I die... and the near truth of that statement makes me think you don't charge enough. ;-)
