Inquiry Regarding Premium Account Payment and Technical Issues for Users in Ukraine

I would like to inquire about the necessity of purchasing a premium account for Ukrainian users. Specifically, does Zoom require users in Ukraine to pay for a premium account if their conferences extend beyond the 40-minute limit?

Secondly, my colleagues and I have encountered recurring technical issues while using Zoom, particularly during conferences where we serve as organizers. At random intervals, we experience sudden disconnections from Zoom. During these occurrences, the screen darkens, and the only resolution seems to be forcibly closing Zoom tasks in Windows or rebooting our PCs and then rejoining the conference. These interruptions significantly disrupt the flow of our meetings and hamper our productivity.

Could you please provide guidance on both matters? Any insights regarding the payment requirements for Ukrainian users and solutions to address the technical issues would be greatly appreciated.

Thank you for your attention to these concerns. I look forward to your response and assistance in resolving these issues promptly.
