[BUG] Update v1.0.51 bugged, let's talk about it

Hello everyone I am a user with MAX x20 plan, in the last days I noticed a drastic drop to Opus4 performance in reasoning for code construction, its strong point let's say. Another problem encountered is the limit of usable tokens per session reduced to 50% less than the last update, and just now I realized that during the session usage from 2pm to 7 pm is completely buggy, because going to check(thanks to CC usage) I realized that the session in use is from 5 pm to 10 pm, and it tells me that I have already reached the limit of Opus4 and I will have written some basic prompts(remember I have the MAX x20 plan).

What can I say, have you noticed the same degradation? let's talk about it, I noticed a lot of similar feedback in other posts on reddit and on cluade code github.
