WePlay Support Refused to Restore My Account After Login Changes

I have been using the WePlay platform for a long time and originally registered my account via my phone number. On 25 May, just before selling my old phone, I logged into my account, used it, and then logged out. After switching to a new phone, I tried to log in again and discovered that I can no longer access my account. After the recent update, the option to log in via phone number has been removed, and now access is only possible if the account is linked to another application. Since my account was created only with a phone number and was not linked to any app, I am now completely unable to log in and use it. I contacted the WePlay developers/support team about this situation, but I was told that they could not help me and that my access could not be restored, which I find very disappointing, as I have an existing account that I actively use. I would like my account to be restored in any possible way, and I am ready to link it to any available application or method you offer. I kindly ask you to help me regain access to my existing WePlay account, as it was created through my phone number, and I do not want to lose it because of this change in the login method.
