I found logging out and back in - or removing the app and reinstalling - fixed this for me.

Delta app just flushed all my manually added (family) trips from my trips. Great, thanks.

Mobile App Not Working Properly
 

Hey everyone, for the last 2 days now me and a friend have both been having issues using the mobile app, not responding, refreshing, lagging, both on separate reservations. Has anyone else been having issues recently?

New one. Tried to change first class seat and app said I had a restriction preventing exit row.

Had this happen to me last weekend. Were you trying to move from 1A to 2A? I was trying to move from 1D to 2D. That message appeared momentarily but it switched the seat anyway and I flew the flight, all was fine. This was an IROP rebooking so I chalked it up to that, but maybe it's actually a broader app bug.

I’ve been getting this message often but the seat change still goes through.

Recently I've had two separate reservations where the app would not save my meal selection in F. Had to call in both times. Both reservations utilized an ecredit but otherwise normal.

And now the app is hitting me with the same bug that numerous others have reported with getting an error message when trying to pre-select a meal.

My app today made me check in twice. First time it appeared to drop my seat assignment and displayed a standby pass without a barcode.

weird

I've had seat assignments not appear when looking at future trips in "my trips", but that's been in both the app and website (but if I check the seatmap my seat selection is still there and when I end up checking in the seat assignment is correct on the boarding pass)

overall I'd say things are generally just buggier now than they've been in a while

maybe Delta is now using WestJet IT.
I had to check in nine times in their app last weekend.
BP didn’t work unless I forced mobile site in safari. Never seen that.

The iphone app is such a glitchy mess. I get the "you don't have enough memory" error daily, but I have plenty of memory.

My going theory is that the app reserves memory and then doesn’t clear it when not needed or when logged out. The out of memory error is particular exasperating when I am managing multiple family member accounts.

Have the same issue on a brand new iPhone 16 Pro with plenty of memory. Usually it happens when trying to book something and I often end up resorting to the website.
