• Does it only happen when synchronization is enabled? If so, which Opera products are connected? (e.g. PC and Opera for Android)
  --> yes, for me PC Opera GX and Opera Android
• Some example sites and how many accounts for one of the reproducing sites? (e.g. we have got a report about Xiaomi account and FB)
  --> many sites are affected, and passwords are even messed up between sites
