I have been using Opera since GX was released, I use it on a Windows 10 PC, a macbook air and two Android devices, a Samsung tablet and a Huawei phone.
Now all my data is synced in my account and everything works on all devices, except the passwords on my Huawei phone.
Opera sync internals on my phone states the following:
Error: MergeSyncData@../../components/password_manager/core/browser/sync/password_sync_bridge.cc:361, datatype error was encountered: Failed to load entries from password store. Encryption service failure.
I have no idea about what to do, the passwords are encrypted and synced on all devices but the phone. Looking at the passwords on my Huawei I have 0. This has been like this for a year now, I hoped at some time it will work but now I am asking for help.
