I have an issue with a specific chat, which i can not delete.
I cleaned up my account recently and deleted a bunch of chats i had. group chats, 1on1 chats and so on. I also deleted the corresponding contacts and deactivated the auto-sync for contacts.
The last one i wanted to delete however keeps reappearing all the time. I can actually delete it on my phone (ios, iphone 12 pro) but whenever i connect a new device this exact chat is still there. Any other chat has been deleted. Its just this single chat.
The contact keeps reappearing with the name "XYZ" which definetly is not their name. Telegram must have decided to call them by that name. This person only sent me one message and i never replied. This was in december 2020.
On most devices i can just delete the chat again and its gone on that device. On some devices it reappears after every update on some its gone forever. However on the web app i cant even delete the chat. I click on delete for or delete for me and them and nothing happens.
I can archive the chat, but this is not a solution for me. Archiving it makes it show up on my phone as well again even though it has been deleted there.
I have many devices from which i connect my account all the time. It is really annoying to have to delete that chat all the time. It does not matter on which device btw. I tried the windows (11) desktop app + web app(firefox), telegram app on a macBook Pro 16 (2019, Intel Cpu), macBook Pro 16 M1 telegram app + web app(chrome), macBook pro 14 M1 telegram app + firefox, iPhone 12 Pro telegram app.
What should i do to fix this? Is it even possible to fix it on my end?
Steps to reproduce
I don't know how to reproduce this on another account but for me all i do to reproduce it is the following:
delete all browser data
open the telegram web app
scan the qr code with my iphone
Look at the chats i have there
Delete the Chat (doesn't matter if just for me or for me and them)
Nothing happens
When i do these steps on any telegram app instead of the web version the chat actually appears to be deleted, but only on that specific device/app
As soon as i delete the app data and connect the app again the chat reappears.
I also tried to terminate all sessions except for my phone, doesn't change the outcome
