Hello! Please let me know what’s wrong with my blynk account that the Terminal doesn’t display fully. I used the sample code at Blynk Example Browser. I created an account in 2019 and subscribed to the blynk plus package of 159,000 VND/month since blynk 2.0 was launched. I created a new free blynk account and the Terminal works fine.
Hello @quocanhtran2701 . Looks like you use iOS app. Please describe in more detail what you meant. Also please write app version.
Thank you for your support. Yes, I am using the IOS app. Let me describe the problem again. I have been using blynk since 2019. About a year ago, I discovered a bug where the Terminal screen did not display when there was a command to display a text sentence. I only saw this bug appear on the account I have used since 2019. I tried creating a new account and the Terminal worked normally on this account. I use the same control program, the same phone, just a different account. I have attached the image, and the program below. I am using hardware is Arduino Mega 2560 with Ethernet Shield W5100.version of Blynk Iot app is 1.64. The subscription package is the Maker package. Please tell me why? Thank you.
/*************************************************************
This example shows how to use Arduino Ethernet shield (W5100)
to connect your project to Blynk.
NOTE: Pins 10, 11, 12 and 13 are reserved for Ethernet module.
DON'T use them in your sketch directly!
WARNING: If you have an SD card, you may need to disable it
by setting pin 4 to HIGH. Read more here:

@quocanhtran2701 we did not found some issue in terminal widget in Maker plan.
A very important detail is that the maker plan has a saving limit of the last 10 lines/values. That is, after refreshing the page or reopening the device, only the last 10 messages will be displayed.
If you have other problems or errors, please describe the problem in more detail.
