looks like I have to leave chess.com after 7 years of support

So My latest subscription  I had with Chess.com ended sometime I believe in September....my window to play got smaller because it made room for ads, but I thought when I put the subscription back in that my screen would return to normal size, and it didn't, I just put another month subscription in to try it out and no change my chessboard is still the same tiny size it was before, not large like when I had the year subscription...I tried theatre mode I tried the top and bottom right corners nothing makes it larger....I cleared cookies, cache restarted on and on nothing....and when I tried a new account, it got bigger automatically.  So why is my main on chess.com not working?  I've tried every step it told me to try, and when I got to support it told me someone will be in contact with me in 3 days or so.  Chess.com, why are things this way ?  Fix my account or I have to leave chess.com and support another chess forum which I really don't want to do.

its actually closer to 10 but I'm pretending I haven't played here forever lol

Have you tried hovering your mouse over the bottom right corner of the board so that the resize board icon appears and then clicking and dragging on that to change the size of the board?

yep it doesn't change, funny thing is when I I first start a game at the very beginning, my board is normal size but as soon as the game starts it toggles back to small......which is annoying to me and I've lost at least 200 rating points because I have to really focus, I shouldn't be losing to 1000 rated players I'm not trying to disrespect but it bothers me so much I cant play a normal game. its sad. Thanks for your help though DAvid I just don't know what else to do.

Does it do the same thing if you log in to your main account using an Incognito / In private browser window?

im not sure about that but I started a new account to see if the problem was only on my main account and sure enough it is, with the new one everything is normal sized. its weird.

Try clearing your browser cache. If that doesn't work, try clearing local storage

I have the same issue with the board in the web version: I can make it smaller but not bigger. The only thing that helps: I try to make it bigger by dragging that arrow (it wont get bigger) and then refresh the page, after that the board expands to its maximum size

already tried as I stated above, nothing works but if I start on a new account its all perfect.

how would I do that sounds confusing

Yeah, it may have to do with a HTML 5 DOM cookie, rather than one of the "normal" cookies that most people are familiar with. Chess.com does make use of HTML 5 DOM Javascript cookies.

Unfortunately, when Google designed HTML 5 back in the late 2000's, they didn't have user privacy in mind (when does Google ever think about user privacy anyway?) because HTML 5 DOM cookies aren't very straight-forward at all to remove. Unlike regular cookies, you can't just go into your browser settings and click "Clear cookies and cache".

If you're using Firefox, then one option would be to create a new browser profile. All of the HTML 5 cookies from your current profile won't carry over, so you'll be on a clean slate of sorts. That might work. But keep in mind that a lot of other things won't carry over as well (such as browser settings, extensions, themes and things like that).

If you're using Google Chrome then, uhh, I'm really not too sure to be honest. In that case, I'd honestly recommend switching to a different Chrome-based browser; such as Brave. Brave is better than Chrome anyway, due to it's in-built ad-blocker and the fact that it's open-source (meaning that you can actually trust it - unlike closed-source browsers like Google Chrome).

Well, I tried

They needed to fix an issue on their end I get to stay yippee me

The issue is still there
