IPad – Why does this I in a black rectangle with a line through appear on the iPad Pro screen, and how to get rid of it permanently

I think FlockDraw would be the best app for you. Although it is a web app, you could use it on an iPad by downloading a free Flash browser such as Puffin Web Browser.

List of Features:

• draw online
• unlimited people in a room
• updates in real time
• different colors
• different shapes
• eraser
• ability to draw lines
• one click saving
• full screen mode
• gallery to save and upload images
• ability to type and draw
• chat

In response to your limitations and requirements:

A: Only one person can draw at a time. - Two or more people can draw

B: Only one color can be in use at a time. - The large variety of colors allow for more than people to draw with different colors

C: You can't erase. - Eraser is provided.

D: Your canvas is limited to one screen - Well, each person can see the same screen so yes they are limited to it. If they wanted to, they could erase their canvas and start with a new one (Not sure what this is asking)

E: Interaction is limited to WiFi. - When you create a session, you are given an unique URL. You can share that URL and allow more than one person to join you session (This does not have to be through Wi-Fi)

F: Interaction is one way: It's essentially a presentation tool. Two people can draw at the same time.

1. Each of us can draw on our iPad at the same time, Whatever we draw appears on the other screen. Yes, drawing simultaneously is a feature.

2. Option for different colors. E.g. He draws in black, I draw in red. There are lots of colors to choose from

3. Ability for either person to erase/modify their work, with a toggle to switch between 'erase mine' vs 'erase evertything under the eraser' Sorry, don't think this is on here. There is only one eraser that has the ability to erase everything.

4. Ability to hit a one button save/mail screen. Yes, you can save the canvas.

5. Ability to scroll/magnify screen. Each iPad has a several viewport on the canvas. You may be able to; I haven't tried it on an iPad

6. Ability to snap and crop a picture and paste into screen. As you are on an iPad, this feature is included, but it may be harder to do on the iPad. But yes, there is a gallery.

7. Inexpensive. - It is completely free online

Note: There is an iPad/iPhone app, but I'm not sure that it is better than the web app. It also costs $2.99.

Prior to the upgrade to iOS 9.02 this was unresolvable without going to an Apple Store with proof of purchase. With 9.02 it you can work around it. The steps I used were:

1. At the Apple ID site, change the Apple ID email to "oldemail@oldcompany.com" -- this will never be verified.
2. On the iPad go to Settings|iCloud - It will ask for the password.
3. I logged on with the correct password - it now greys out the entire iCloud area and puts a Validate Email message at the top of the form, BUT does not grey out the Sign out.
4. I Signed out and it asked for the password twice again, paused for a long time and then was asking for a new iCloud Apple ID.
5. Back at the Apple ID site, change the Apple ID back to the valid account.
6. From the mail client, validate the Account with the correct password.
7. On the iPad, Settings|iCloud enter the new Apple ID and password.

Poof - problem solved
