Screenshots

Desktop (please complete the following information):
Additional context
I am using the free version of Todoist.
This is what I see in the Terminal:
(com.github.alainm23.planner:2): Gtk-CRITICAL **: 11:38:39.546: gtk_box_pack: assertion '_gtk_widget_get_parent (child) == NULL' failed

Cannot get default EGL display: EGL_BAD_PARAMETER
Cannot create EGL sharing context: invalid display (last error: EGL_SUCCESS)
(WebKitWebProcess:14): Gdk-ERROR **: 11:38:57.814: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.
The error was '179'.
(Details: serial 197 error_code 179 request_code 155 (unknown) minor_code 21)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Have you installed Planner from Flathub?
Yes, I did.
I had the same problem in elementary OS Hera (Ubuntu 18.04) but I thought I had solved it.
I will keep track of it, thanks for reporting it.
I have a very similar situation except that, rather than a blank form after logging in, I am taken to the projects Github page. Is this worth making a separate issue for?

Same issue with me here. Infact I am commenting from the window that opened up inside Planner.
I installed the rpm version on Fedora 32(2.3.5-1.fc32). Flathub version is 959.5 mb!!
yeah, i had the same issue as the github one
I have the github redirect problem too - I'm also using a free Todoist account.
Something that might be relevant (?) is that this is the second Planner installation that I'm trying to link to the same Todoist account.
Linking/login worked on my laptop, but it does not work on my desktop. Both are running elementaryOS and Planner 2.4.
@cameralibre Solved, update to 2.4.4
Yep. Solved.
I guess this issue can be closed now?
This issue appears to discuss two different bugs:
