Hello @nab0y4enko,
I checked up this issue.
We will modify the logic of caching files to separate them from the main queue.
And, modified version will be deploy this week.
Sorry for the late confirmation, Thanks for the reporting!
Thanks. Looks like already fixed in last version!
@nab0y4enko
Oh, you already checked the last version!
The last version is 2.2.2.
Thank you!
