Hi 😄 ; please understand that as the affected service is a paid-for one that requires an active valid account to get access to video streams (which, in all probability, should be geo-fenced outside of Turkey), it's near impossible for others (the browser author included 😜 ) to troubleshoot this any further...

Since you're on Win7 SP1 x64, my advice to you is try the latest FirefoxESR-115.18.0 (32 or 64-bit), which is the ONLY browser that fully supports DRM (and latest Widevine CDM v4.10.2830.0) under Win7 (and this is only until the end of April 2025) ; if the TV+ platform does work there, then one additional thing to try and get it working on latest Supermium is:

With Supermium exited, navigate (in Widows Explorer) to its main application directory (you can get that info by previously loading chrome://version/ and looking for "executable path"); verify that a widevine_patch.exe executable and win7_fixwidevine.cmd batch file are present there; run the batch file (Supermium should be closed; the cmd file runs silently, don't expect any output from it).
Launch the browser and visit

If the video loads and plays (with Widevine), then you have successfully patched Widevine CDM; you can then proceed to try TV+ anew; if still no go, then the service does require the Verified Media Path (VMP) security feature, which ISN'T available in Supermium (because it requires a fee in the USD1,000s range to be paid to Google, owners of Widevine, and, even if that sum were collected and paid, it's still unsure whether evil Google 😠 would be OK with an open-source browser like Supermium) ...

It's most sad 😞 that it's in the nature of DRM itself 👎 to limit users on which devices (and this entails the OS, too) protected content can be viewed; but the masses remain apathetic to DRM, despite petitions by the EFF and others, so media rights owners tend to employ it everywhere 👎 nowadays...
