Having the same issue for months.

I have 2 PC-s connected to my android phone. It ALWAYS disconnects from either one from the PC's including the data sync and flow as well. There is no warning, no information, nothing, at the time when I understand what is going on, I have lost dozens of bookmarks and it is really really frustrating.

I have wrote emails to opera support, i have reported bugs and I have wrote this in 'suggestions how to improve" yet no answer and no fix. I have this issue at least 8 months.

Additionally I have reset everything and reconnect successfully just about 2 weeks ago and today i got the same problem again. I don't think that anything works and I think it's their internal issue.

Probably I`ll switch to brave browser after using opera for 5 years.

Edit: Possible fix is this but don't expect to be a long term solution, usually it disconnects very often.
Go to opera.com/connect -> scan the QR code with your phone -> confirm numbers.

So as the title states I have few issues with opera gx browser for some longer (years) period. So it were not fixed by now so I have to publicly address each issue:
Extensions/add-on/plugin issues :

1. Extensions keep auto-deleted by opera without my consent
2. No sync option for extensions. Installing opera on new pc is painfully bad because I have to manually search and install each extension by my self
3. "Pack Extension" and "Load Unpacked" is literally useless and buggy. It also does not work as you would assume that it works, especially if you want to migrate extensions between 2 computers. Additionally, manually installing an extension (eg. from github) is painfully tough to do

Sync Issues:

1. Constantly in period between few months my opera browsers "de-sync" / account disconnects without giving any information for that (this happens on all of my computers). Everything that I have saved (password, bookmark, flow link/text etc...) while my account was disconnected is going to be overwriten by the last settings I had at the moment when my account was mysteriously disconnected
2. On literally every update my settings in the GX Corner are being reset on each category to "On". I think this is happening on every opera update but I am not 100% sure. But it usually gets reset every ~1-2 days

Vesion:
LVL4 (core: 94.0.4606.107)
Update stream:Early Access
System:Windows 10 64-bit
Chromium version:108.0.5359.125

So apparently this issue (for me) exists for more than a year. Just randomly Opera GX keep deleting some of my extensions without my consent. It also never informs me that an extension is going to be deleted or that it has been deleting. I can not state the time after an extension is being deleted, but it goes:

• Immediately after installing an extension and I close and re-open opera GX
• After few days, weeks or even months.

I am absolutely sure that this is not an issue with my PC/Antivirus/Version of opera or any 3rd party application/process problem. This is happening on 3 different PC/Laptops at home. Most weird fact is that I have the same extensions on all devices yet on some, some of the extensions is deleted immediately, on some it remains for some time and on some it stays forever. It is completely random behavior and it is driving me crazy.

Opera GX auto update is enabled and extensions auto-update is also enabled. Current Opera GX detalis are:

LVL4 (core: 94.0.4606.107)
Update stream:Early Access
System:Windows 10 64-bit
Chromium version:108.0.5359.125

Any way how can avoid this behavior and prevent opera of auto-managing my extensions?
