So first of all the "assignment" tab problem half of the time it wont even load making the user have to leave the app and rejoin taking too much time second one so when I join meetings I have seen that my screen sometimes keeps flashing into a black screen some lasting for only 1 or 2 sec sometimes longer im confused why that happens it only happens when I use your app so fix that and last one is that when I join meetings it takes so long just to get in causing me to be late.I have good internet
