That's so annoying.
I'm struggling with information from schools now as I have 4 apps across 2 schools, plus emails, 5 minute videos on one of the apps containing one sentence of vital information plus the occasional paper letter.
Oh, and the primary uses 2 ways to prebook hot dinners somewhere between 1 and 4 weeks in advance based on the patterns of the moon or some such thing.
I feel like I am constantly trying to chase bits of scattered information and have so far missed DS' last primary Christmas lunch booking, one primary parents evening, I have had to chase information for a trip I had paid for but had no idea when it was or that I needed to pick DD up at 9pm, (the one paper letter this year) and DD had a surprise double vaccination yesterday as I had filled in the consent form weeks ago with no date given and then missed the mention of the date on one of the apps, or was it in an email, or on the school website calendar?
I just found out DS has topic homework which we have never done as it is only on the year group section of the school website. Luckily it is voluntary as neither of us knew about it and we're just vaguely confused that sometimes children would turn up at school with papier-mâché models of the solar system. I just thought they had very keen parents.
This is harder work than my actual full time job.
Sorry, rant over, but I feel your pain and would be very annoyed in your position. I would have expected the school to send another email or whatever for a while year trip.
