Hi Littlejames77,
Edit after typing: Sorry my mistake. I thought you would switch from ABN to a digital bank, but you keep your ABN-account as your first bank (or not?). So not everything is that relevant anymore, but I will keep it this way, maybe someone else finds it useful in 1 way or another.
In your case, if you open a second digital bank account for savings, I wouldn't put to much money on it. "real" banks or fintech banks with a valid EU banking license are mostly part of a fund that gives you back your money when they go bankrupt. (in Holland till 100.000 euro pp right now). Not all fintechs are part of such a fund or are officially a bank, so check this first! And better separate your money between 2 or more banks, also your savings. I don't know what the interests and exact offers are right now, but most of the fintechs who offer savings in 1 way or another are free, so you could try them first (and also use them for example for the free debit master- or visacard with much cheaper rates on holidays etc.).
Extra tip: a list of (not so fintech, mostly Dutch) banks with interests on savings. Maybe you can open an account there as well, if you want:

No still no IDEAL with N26.
N26 has a real banking license, same as Bunq and Openbank. Revolut I still don't know if they have/had and if it changed or if it's (still?) valid, they weren't very clear on that.
Further: check OpenBank, Revolut, N26, Bunq etc. -websites for there offers, possibilities and rates on savings etc. It all changes now and then.

First answer, before edit:
I would stay with ABN for several reasons. It's one of the big banks in the EU/The Netherlands. Not really worth all the troubles to switch everything for only almost zero interest on savings. And don't forget, with many digital banks or fintechs you don't get a dutch Iban (but a Spanish, British or German one) this can cause problems at some point! Not every service or company works with foreign iban-accounts (although I think they should by now, according to EU-law).
Also, only Dutch banks have identification by IDIN (it is called I guess, something like that), maybe you need that sooner or later. Foreign banks or fintechs have no IDEAL and Tikkie. Only (real) banks, not many fintechs are backed up by the national Dutch/EU fund that gives you back your money when they go bankrupt (till 100.000 euro pp right now). With ABN you can put cash-money on your account at a machine. ABN still has offices which you can go to if you have problems of any sort. ABN is one of the few banks right now, who uses all 3 systems for instant payments in NL and the EU etc etc.
I think N26 still hasn't IDEAL. Why should they, for just a few dutch customers and probably it costs them money.
Why don't you open 1 or 2 extra accounts just for savings.... and keep your ABN as vital primary bank. I always advice to keep 1 "normal" "old" bank at least. Or you can open a free Revolut , N26 or Openbank + savings option or.......X account as an extra. Or several. Most of them are (still) free.
Or save at 1 of the other mostly Dutch banks:

I don't work for ABN but it has it pro's in my opinion. ING a good alternative I think (but only have 1 of the 3 instant payments systems implemented right now, but I like the ING app en possibilities more). Also have many of the digital banks myself, but still don't trust them with bigger amounts. Quite often you read that someones account is totally frozen and they are being investigated, which can take a while. Traditional banks are better with that, I think.
