If you have any difficulties when working with the bot, you can contact the developer, but first of all:
Is everything done right? First you need to check if there is an answer to it in the FAQ. If the question is of a technical nature for any of the bot tools, then most likely the answer to it is in the description of the corresponding tool in the documentation.
Are you using the latest version of the bot? You need to restart the bot and make sure that it does not offer to update.
Does the bot stop? Code notices are not always errors. If the bot has not stopped, then everything is fine. If the same notification appears for a long time - see what it means on this page.
If you have any questions, you can ask them to the administrator via Telegram.
