I called them last week and asked 3 questions. The first was about leaving my current employer, he said that as long as you have your open work permit, everything should be fine.
The second question was about the status of the application, he said that my application has not exceeded 19 months and he can't tell me anything.
And the last question was about benefits for Ukrainians and if there was any way to speed up the process, he said there was nothing like that right now, but mentioned that the officer would see where I was from and should understand the situation. I won't say that the last question helped somehow, maybe it was just a coincidence.
Anyway, I hope you get some good news soon
