It appears that the indexing system stopped working, I tried with sentences I added earlier today and they aren't indexed yet

I am not sure how this will play out for the Uzbek language. There is still time, though... As for the Tatar language, the issue of transliteration — converting between the Cyrillic and Latin scripts (specifically the Zamanalif-2012 system) — was raised repeatedly on this site more than two months ago. Yet, things remain exactly as they were. Meanwhile, industry leaders in the field of language — such as Google (with its translator and artificial intelligence), DeepL, and ChatGPT — have successfully addressed the challenges of understanding, translating, and writing the Tatar language in both Cyrillic and Latin scripts. I would like to express my immense gratitude and appreciation to these platforms for their work!

Tuntematta kieltä tai poliittista tilannetta, ajattelen että vanhat lauseet olisi hyvä säilyttää. Kenties niihin voi lisätä tunnisteen (tag) vanhasta kirjoitusasusta. Sitten voi harkintansa mukaan tehdä uusia lauseita uudella kirjoitusasulla.

Microsoft began translating content into the Tatar language in 2005, Yandex in 2015, and Google in 2020. DeepL followed somewhat later, but it began translating Tatar texts written not only in the Cyrillic script but also in the Latin script. Now, Google also translates Tatar texts written in the Latin script just as effectively as those in Cyrillic. I would like to express my heartfelt thanks to the employees of these companies for their tremendous work!

We also very much hope that Google will soon begin to speak the Tatar language, just as ChatGPT, Yandex, TatSoft, and others have been doing quite well for some time now.

Yes, there are some, if I remember right.

I don't really understand what the point of your question is.
There are some suggestions to change a sentence and the contributor can change that; if not, a corpus maintainer can change that.
(Some sentence seem not to be correct, however some of them are correct in a region which we don't know.
And e.g. in Hungarian many contributors always add an unnecessary indefinite article before nouns [Anglicism; Ez alma :) —> Ez egy alma :( / This is an(/one) apple] which I find ugly in Hungarian but they can't imagine our language other way so as the society can't imagine the life without smart phones now.
I'd change all those sentences.)
(The Hungarian sentences are controlled, anyway.)

I tag my sentences with that if I give to the sentence an explanation (as a translation aid).
(That tag already existed, I just use it.)
In fact, it doesn't have too much sense (yet), since one can only see the tag when one openes the sentence.
