Hello,
reporting back from my attempts to overcome my current data lock-in 
Even after some Gramps Web and API Updates, the same issues still occur as detailled in this thread as well as the one with exporting I wrote about here (also see last post).
→ So what are my options right now?
Is there any options to “manually” search for corrupted data?
Or might it be best to manually add Gramps Web Changes to my Gramps Desktop and start over?
(also haven’t tried exporting my data via other export options apart from Gramps XML - but as far as I know I’ll lose data when using them)
Thankful for any advice!
