Timezone issue

Hello dear DoIt team,

I'm facing with a really strange timezone issue.
And it's actually appear in both website and Android app.

Could you assist me with this please?

After I've set a timezone for my particular location (before it was UTC+2 and now - UTC+1) all my Tomorrow tasks appear as a Today tasks, and Today tasks display as already expired.
How this could be fixed?

And even staying within a previous UTC+2 timezone now (in the Settings, of course)
the time frame for all corresponding tasks began to be expired in an hour earlier. For instance time for task set for 10 AM displays as already expired at 9.10 AM.

Looking forward for your reply.

Best wishes!
